DESCRIPTION
Compile switch constants
Constant: VSTR_COMPILE_ATTRIBUTES
Explanation:
This switch controls whether gcc type __attribute__() statements are
used in the public headers headers for the library. If the value is 1
then if they are supported by the compiler that built the library they
will be used, if the value is 0 they won't be used at all.
Constant: VSTR_COMPILE_INCLUDE
Explanation:
This switch controls whether including <vstr.h> will include all the
system headers needed for the exported interfaces. If the value is 1
then if they are included, if the value is 0 they won't be included.
Constant: VSTR_COMPILE_INLINE
Explanation:
This switch controls whether inline functions will be used in the
public headers for the library. If the value is 1 then if they are
supported by the compiler that built the library they will be used, if
the value is 0 they won't be used.
Constant: VSTR_COMPILE_MACRO_FUNCTIONS
Explanation:
This switch controls whether macro functions will be used in the
public headers for the library. If the value is 1 then they will be
used, if the value is 0 they won't be used.
Note:
This only includes the macro functions which also have real function
replacements. For example VSTR_ADD_CSTR_BUF() won't be defined because
there is a vstr_add_cstr_buf() function, but VSTR_FMT_CB_ARG_PTR() will
always be defined.
Constant: VSTR_COMPILE_TYPEDEF
Explanation:
This switch controls whether typedef will be used for the structs in
the public headers for the library. If the value is 1 then they will be
used, if the value is 0 they won't be used at all (and your code will
have to use struct tags instead -- note all libraries using vstr should
compile with this option set).
Global constants
Constant: VSTR_MAX_NODE_ALL
Explanation:
This is the largest size a node can be, if you pass values greater
than this to vstr_add_ptr() etc. then multiple nodes will be allocated.
Constant: VSTR_MAX_NODE_BUF
Explanation:
This is the largest size a node _BUF type can be, if you pass values
greater than this to vstr_add_buf() etc. then multiple nodes will be
allocated.
Constants passed to vstr_make_spare_nodes() and vstr_free_spare_nodes()
Constant: VSTR_TYPE_NODE_BUF
Explanation:
This type when passed to vstr_make_space_nodes() specifies nodes of
type _BUF, which are the only nodes that can be "written" to. These
nodes are added into a Vstr string by the vstr_add_buf() function and
the vstr_add_iovec_buf_*() functions.
Note:
A call to vstr_sub_buf() with a Vstr string consisting of _BUF nodes
means that data will be substituted inplace.
Constant: VSTR_TYPE_NODE_NON
Explanation:
This type when passed to vstr_make_space_nodes() specifies nodes of
type _NON, which are nodes that contain "nothing". These nodes can be
used as placeholders for data, and are added into a Vstr string by the
vstr_add_non() function.
Constant: VSTR_TYPE_NODE_PTR
Explanation:
This type when passed to vstr_make_space_nodes() specifies nodes of
type _PTR, which are nodes that contain a memory pointer to an area of
memory.
Constant: VSTR_TYPE_NODE_REF
Explanation:
This type when passed to vstr_make_space_nodes() specifies nodes of
type _REF, which are nodes that contain a Vstr memory reference.
Constants passed to vstr_add_vstr() and vstr_sub_vstr()
Constant: VSTR_TYPE_ADD_DEF
Constant: VSTR_TYPE_SUB_DEF
Explanation:
This type when passed to either vstr_sub_vstr() or vstr_add_vstr()
specifies that all types of nodes are added as their respective type.
Constant: VSTR_TYPE_ADD_BUF_PTR
Constant: VSTR_TYPE_SUB_BUF_PTR
Explanation:
This type when passed to either vstr_sub_vstr() or vstr_add_vstr()
specifies that all nodes of type _BUF are added as type _PTR.
Note:
If you add/del/sub data in the original Vstr string then because the
added data is only pointers to the old data, life may become
interesting for you.
Constant: VSTR_TYPE_ADD_BUF_REF
Constant: VSTR_TYPE_SUB_BUF_REF
Explanation:
This type when passed to either vstr_sub_vstr() or vstr_add_vstr()
specifies that all nodes of type _BUF are converted to type _REF before
being added.
Note:
This means that if you do a substitution on the original Vstr string
it will now be less efficient, as the _REF nodes cannot have data
substituted in place.
The _BUF nodes will not go back to the pool in the Vstr configuration
as happens if you deleted them.
Constant: VSTR_TYPE_ADD_ALL_REF
Constant: VSTR_TYPE_SUB_ALL_REF
Explanation:
This type when passed to either vstr_sub_vstr() or vstr_add_vstr()
specifies that the data should be taken as though vstr_export_ref() was
called on the original Vstr string.
Constant: VSTR_TYPE_ADD_ALL_BUF
Constant: VSTR_TYPE_SUB_ALL_BUF
Explanation:
This type when passed to either vstr_sub_vstr() or vstr_add_vstr()
specifies that the data should all be added via. vstr_add_buf().
Constants passed to vstr_fmt_add()
Constant: VSTR_TYPE_FMT_END
Explanation:
This flag means that there are no more arguments to be expected.
Note:
Because you can have multiple arguments associated with one custom
"fmt" specification this has to be the last argument to every call to
vstr_fmt_add().
Just specifying this type means that there are no arguments used, by
the custom "fmt" specification.

from the argument list passed to it
Constant: VSTR_TYPE_FMT_UINTMAX_T
Explanation:
This flag means that vstr_add_vfmt() should expect a "uintmax_t" type
from the argument list passed to it
Constant: VSTR_TYPE_FMT_DOUBLE
Explanation:
This flag means that vstr_add_vfmt() should expect a "double" type
from the argument list passed to it
Constant: VSTR_TYPE_FMT_DOUBLE_LONG
Explanation:
This flag means that vstr_add_vfmt() should expect a "long double"
type from the argument list passed to it

type from the argument list passed to it
Constant: VSTR_TYPE_FMT_ERRNO
Explanation:
This flag means that vstr_add_vfmt() should not expect any arguments
passed, but should set the value of errno, just before calling the user
callback, to the value upon entering vstr_add_vfmt().
Constants returned from vstr_iter_fwd_*()
Constant: VSTR_TYPE_ITER_DEF
Explanation:
This return flag is 0, and is generally only used as programmer
documentation to mean nothing special is meant for this data.
Constant: VSTR_TYPE_ITER_END
Explanation:
This return flag means that the data is at an end.
Constant: VSTR_TYPE_ITER_NON
Explanation:
This return flag means that the data is actually from within a node
of type VSTR_TYPE_NODE_NON.
Constants passed to vstr_sc_fmt_cb_beg()
Constant: VSTR_FLAG_SC_FMT_CB_BEG_DEF
Explanation:
This flag is the same as just specifying
VSTR_FLAG_SC_FMT_CB_BEG_OBJ_STR.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_STR
Explanation:
This flag indicates that the object should be treated as a C style
string, so it is assumed that number orientated flags should be ignored
and that the length of the object can be arbitrarily truncated.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_ATOM
Explanation:
This flag indicates that the object should be treated as an atomic
piece of data, so it is assumed that number orientated flags should be
ignored and that the length of the object can't be truncated.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NUM
Explanation:
This flag indicates that the object you are printing should be
treated as a number. For instance setting a precision will truncate the
length of the object, unless it is a number. Also +/-/<space> leaders
and zero padding will only be done for numbers.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NEG
Explanation:
This flag indicates that the number object you are printing should be
treated as negative number. This flag has no meaning if
VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NUM is not set.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_HEXNUM_H
Explanation:
This flag indicates that the number object you are printing should be
treated as an uppercase hexadecimal (base 16) number. This flag has no
meaning if VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NUM is not set.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_HEXNUM_L
Explanation:
This flag indicates that the number object you are printing should be
treated as a lowercase hexadecimal (base 16) number. This flag has no
meaning if VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NUM is not set.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_OCTNUM
Explanation:
This flag indicates that the number object you are printing should be
treated as octal (base 8) number. This flag has no meaning if
VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NUM is not set.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_BINNUM_H
Explanation:
This flag indicates that the number object you are printing should be
treated as an uppercase base 2 number. This flag has no meaning if
VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NUM is not set.
Constant: VSTR_FLAG_SC_FMT_CB_BEG_OBJ_BINNUM_L
Explanation:
This flag indicates that the number object you are printing should be
treated as a lowercase base 2 number. This flag has no meaning if
VSTR_FLAG_SC_FMT_CB_BEG_OBJ_NUM is not set.
Constants passed to vstr_conv_unprintable_del() and
vstr_conv_unprintable_chr()
Constant: VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_NONE
Explanation:
This flag is 0, and is generally only used as programmer
documentation to mean no flags are applied to this function.
Note:
Because it is sometimes hard are to notice certain characters, they
are classified as "unprintable" by default, the value
VSTR_FLAG_CONV_UNPRINTABLE_DEF is a default that is what most people
would expect to be classified as unprintable.
Constant: VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_NUL
Explanation:
This flag allows the ASCII 0x00 byte, aka. NULL, through as a
"printable" character.

"printable" character.
Constant: VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_HT
Explanation:
This flag allows the ASCII 0x09 byte, aka. horizontal tab, through as
a "printable" character.
Constant: VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_LF
Explanation:
This flag allows the ASCII 0x0A byte, aka. line feed, through as a
"printable" character.
Constant: VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_VT

"printable" character.
Constant: VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_HSP
Explanation:
This flag allows the ASCII 0xA0 byte through as a "printable"
character.
Note:
The value 0xA0 is 0x20 with the high bit set, and this character it
often printed as space when in an ASCII like encoding.
Constant: VSTR_FLAG_CONV_UNPRINTABLE_ALLOW_HIGH
Explanation:
This flag allows the all ASCII bytes greater than or equal to 0xA1
through as "printable" characters.
Note:
This includes all the extra characters like not, degree, copyright
and micro when in an ASCII like encoding.
Constant: VSTR_FLAG_CONV_UNPRINTABLE_DEF
Explanation:
This flag is the same as using the flags for space, comma, dot and
underbar. Using just this flag is probably what you'd expect an
"unprintable" function to do.
Constants passed to vstr_parse_num() etc.
Constant: VSTR_TYPE_PARSE_NUM_ERR_NONE
Explanation:
This error code has the value 0, and means that no error occurred
parsing the number from the Vstr string.
Constant: VSTR_TYPE_PARSE_NUM_ERR_ONLY_S
Explanation:
This error code means that the Vstr string consisted only of spaces.
Constant: VSTR_TYPE_PARSE_NUM_ERR_ONLY_SPM
Explanation:
This error code means that the Vstr string consisted only spaces, and
a plus or minus sign.

Explanation:
This error code means that the Vstr string consisted only spaces, a
plus or minus sign and a "0x" base 16 prefix.
Constant: VSTR_TYPE_PARSE_NUM_ERR_OOB
Explanation:
This error code means that the Vstr string had characters in it that
where out of bounds from the working set.
Note:
This out of bounds includes the Vstr string "++" as well as "4A",
when parsing in a base less than 11.
Constant: VSTR_TYPE_PARSE_NUM_ERR_OVERFLOW
Explanation:
This error code means that the number parsed from the Vstr string
would overflow the type it is being parsed into, this is only returned
when the VSTR_FLAG_PARSE_NUM_OVERFLOW flag was passed to the parse
function.
Constant: VSTR_TYPE_PARSE_NUM_ERR_NEGATIVE
Explanation:
This error code means that the number parsed from the Vstr string
starts with a '-' (Hyphen) character when it is supposed to be an
unsigned type.
Constant: VSTR_TYPE_PARSE_NUM_ERR_BEG_ZERO
Explanation:
This error code means that the number parsed from the Vstr string
starts with a '0' (Digit Zero) character, when the
VSTR_FLAG_PARSE_NUM_NO_BEG_ZERO flag was passed to the parse function.
Constant: VSTR_FLAG_PARSE_NUM_DEF
Explanation:
This flag is 0, and is generally only used as programmer
documentation to mean no flags are applied to this function.
Constant: VSTR_FLAG_PARSE_NUM_LOCAL
Explanation:
This flag changes the parsing from ASCII numbers into "local" numbers
(whatever is generated by '0 .. '9' by the host compiler). This can be
ignored by anyone not using an EBCDIC character set, or something
equally weird.
Constant: VSTR_FLAG_PARSE_NUM_SEP
Explanation:
This flag allows the parsing of the '_' (Low Line) separator
character between the digits of the number, so "1234" and "1_234" would
both parse the same.
Note:
The separator is only allowed within the digits of the number, so "
_+_1234" would fail as would "_1234".
Constant: VSTR_FLAG_PARSE_NUM_OVERFLOW
Explanation:
This flag turns on the overflow checking, in other words without it
VSTR_TYPE_PARSE_NUM_ERR_OVERFLOW will never be returned as an error
code.
Note:
The return value with this set is the highest number that can be
parsed from the beginning of the Vstr string, while the value without
this flag would be the parsed number modulo the highest number of the
type.
For example given a type that had a maximum of 10, then parsing "64"
would give you 6 with the flag, and 4 without.
Constant: VSTR_FLAG_PARSE_NUM_SPACE
Explanation:
This flag allows one or more ' ' (Space) characters before the number
or number prefix (Plus Sign, Hyphen).
Constant: VSTR_FLAG_PARSE_NUM_NO_BEG_ZERO
Explanation:
This flag disallows one or more '0' (Digit Zero) characters before
the number.
Constant: VSTR_FLAG_PARSE_NUM_NO_BEG_PM
Explanation:
This flag disallows a plus or a minus character before the number.
Constant: VSTR_FLAG_PARSE_NUM_NO_NEGATIVE
Explanation:
This flag disallows negative values.
Note:
While this flag can be passed to vstr_parse_int() etc. it is most
useful when passed to the generic function vstr_parse_num().
Constants passed to vstr_parse_ipv4()

127.0.0.1/255.0 is an ipv4 address with a non full ipv4 netmask).
Constant: VSTR_FLAG_PARSE_IPV4_DEF
Explanation:
This flag is 0, and is generally only used as programmer
documentation to mean no flags are applied to this function.
Constant: VSTR_FLAG_PARSE_IPV4_LOCAL
Explanation:
This flag changes the parsing from ASCII numbers into "local" numbers
(whatever is generated by '0 .. '9' by the host compiler). This can be
ignored by anyone not using an EBCDIC character set, or something
equally weird.
Constant: VSTR_FLAG_PARSE_IPV4_ZEROS
Explanation:
This flag allows the use of leading zeros in the ipv4 address and
masks.
Constant: VSTR_FLAG_PARSE_IPV4_FULL
Explanation:
This flag changes the parsing so that the function will return an
error if a non full ipv4 address is given (Ie. 127/8 is a non full ipv4
with a CIDR mask). If this flag isn't given the missing numbers are
assumed to be zero.
Constant: VSTR_FLAG_PARSE_IPV4_CIDR
Explanation:
This flag allows the parsing out of a CIDR mask, if one is present.
Constant: VSTR_FLAG_PARSE_IPV4_CIDR_FULL
Explanation:
This flag changes the parsing so that the function will return an
error if a non full ipv4 CIDR mask is given (Ie. 127.0.0.1/ is an ipv4
with a non full ipv4 CIDR mask). If this flag isn't given the missing
CIDR mask is assumed to be 32.
Constant: VSTR_FLAG_PARSE_IPV4_NETMASK
Explanation:
This flag allows the parsing out of a ipv4 netmask, if one is
present.
Note:
If both this and the VSTR_FLAG_PARSE_IPV4_CIDR flag is given, then
either masking interface will be parsed out (it will try a CIDR mask
first and if that filas, fall back to a netmask prefix).
Constant: VSTR_FLAG_PARSE_IPV4_NETMASK_FULL
Explanation:
This flag changes the parsing so that the function will return an
error if a non full ipv4 NETMASK mask is given (Ie. 127.0.0.1/255.0 is
an ipv4 with a non full ipv4 netmask). If this flag isn't given the
missing numbers are assumed to be zero.
Constant: VSTR_FLAG_PARSE_IPV4_ONLY
Explanation:
This flag changes the parsing so that the function will return an
error if the entire string isn't used to contain the ipv4 and option
mask.
Note:
When this error code is returned, the ip address is still parsed out
and as usable as if no error had occurred.
Constants passed to vstr_parse_ipv6()

is an ipv6 address with a non full ipv6 CIDR mask).
Constant: VSTR_TYPE_PARSE_IPV6_ERR_IPV6_NULL
Explanation:
This error code means that there is more than one "NULL" point in the
ipv6 address, for example "F::E::1" has two NULL points and is
impossible to parse.
Constant: VSTR_FLAG_PARSE_IPV6_DEF
Explanation:
This flag is 0, and is generally only used as programmer
documentation to mean no flags are applied to this function.
Constant: VSTR_FLAG_PARSE_IPV6_LOCAL
Explanation:
This flag changes the parsing from ASCII numbers into "local" numbers
(whatever is generated by '0 .. '9' by the host compiler). This can be

Explanation:
This flag changes the parsing so that the function will return an
error if a non full ipv6 CIDR mask is given (Ie. ::1/ is an ipv6 with a
non full ipv6 CIDR mask). If this flag isn't given the missing CIDR
mask is assumed to be 32.
Constant: VSTR_FLAG_PARSE_IPV6_ONLY
Explanation:
This flag changes the parsing so that the function will return an
error if the entire string isn't used to contain the ipv6 and option
mask.
Note:
When this error code is returned, the ip address is still parsed out
and as usable as if no error had occurred.
Constants used with the custom output formatter for ipv6 addresses
Constant: VSTR_TYPE_SC_FMT_CB_IPV6_ALIGNED
Explanation:
This flag outputs the ipv6 address as 8 groups of 4 hexadecimal
values. For example "FFFF:0EEE:00DD:000C:0000:0000:0001:0002" would be
an ipv6 address output in aligned mode.
Constant: VSTR_TYPE_SC_FMT_CB_IPV6_COMPACT
Explanation:
This flag outputs the ipv6 address in as small a representation as
possible, for example "FFFF:EEE:DD:C::1:2" would be an ipv6 address
output in compact mode.
Constant: VSTR_TYPE_SC_FMT_CB_IPV6_STD
Explanation:
This flag outputs the ipv6 address as 8 groups of hexadecimal numbers
between 0 and FFFF, this is the format mostly used in standards.
documents, for example "FFFF:EEE:DD:C:0:0:1:2" would be an ipv6 address
output in compact mode.
Constant: VSTR_TYPE_SC_FMT_CB_IPV6_IPV4_ALIGNED
Explanation:

VSTR_SPLIT_CSTR_BUF(), vstr_split_chrs(), vstr_split_cstr_chrs() and
VSTR_SPLIT_CSTR_CHRS()
Constant: VSTR_FLAG_SPLIT_DEF
Explanation:
This flag is 0, and is generally only used as programmer
documentation to mean no flags are applied to this function.
Constant: VSTR_FLAG_SPLIT_BEG_NULL
Explanation:
This flag allows the split functions to add sections at the beginning
of the input that have a null string before the match. For example the
input "::abcd:..." split on ":" would have 2 sections at positions 1
and 2 of length 0, without this flag the first section would be at
position 3 with length 4.
Constant: VSTR_FLAG_SPLIT_MID_NULL
Explanation:
This flag allows the split functions to add sections in the middle of
the input that have a null string between 2 matches. For example the
input "a::abcd:..." split on ":" would have the second section at
position 3 of length 0, without this flag the second section would be
at position 4 of length 4.
Constant: VSTR_FLAG_SPLIT_END_NULL
Explanation:
This flag allows the split functions to add sections at the end of
the input that have a null string after a match. For example the input
"a::" split on ":" would have the second section at position 3 of
length 0, without this flag there would only be one section added.
Constant: VSTR_FLAG_SPLIT_POST_NULL
Explanation:
This flag allows the split functions to add a final post section of
the input that ends with a match. For example the input "a:" split on
":" would have the second section at position 3 (outside the range of
the input) of length 0, without this flag there would only be one
section added.
Constant: VSTR_FLAG_SPLIT_NO_RET
Explanation:
This flag allows the split functions to return 1, when the Vstr
sections doesn't have any more room. Without the flag the split
functions would calculate the number of splits that would have been
added if there was room in the Vstr sections.
Constant: VSTR_FLAG_SPLIT_REMAIN
Explanation:
This flag changes the split functions, when used with a limit, so
that the last section added is for the remainder of the input.

sections backward (from the end to the beginning).
Constant: VSTR_FLAG_SECTS_FOREACH_ALLOW_NULL
Explanation:
This flag changes the foreach function so that it calls the foreach
callback on sections of null length (a non zero position with a zero
length).
Constant: VSTR_TYPE_SECTS_FOREACH_DEF
Explanation:
This return value is 0, and is generally only used as programmer
documentation to mean nothing special should happen on return from the
callback.
Constant: VSTR_TYPE_SECTS_FOREACH_DEL
Explanation:
This return value tells the foreach function to delete the current
section before the next callback is called.
Constant: VSTR_TYPE_SECTS_FOREACH_RET
Explanation:
This return value tells the foreach function to return immediately
(it does the same thing as a break statement in a C for loop.
Constants used with the callback from vstr_cache_add_cb()

Explanation:
This type means that a delete operation has just happened on the Vstr
string, the position and length arguments are as taken from the
vstr_del() function.
Constant: VSTR_TYPE_CACHE_SUB
Explanation:
This type means that a substitute operation has just happened on the
Vstr string, the position and length arguments are as taken from one of
the vstr_sub_* functions.
Constant: VSTR_TYPE_CACHE_FREE
Explanation:
This type means that the data in the cache needs to be free()'d, the
callback should always return NULL when this type is passed in.
The position and length arguments are undefined.

Explanation:
This error code means that the call to mmap() returned -1, errno is
set.
Constant: VSTR_TYPE_SC_MMAP_FILE_ERR_CLOSE_ERRNO
Explanation:
This error code means that the call to close() returned -1, errno is
set.
Note:
Even though this is an error, the mapping has already occurred and
was successful.
If another error occurred (Eg. fstat()/mmap()), then any errors from
close() will be hidden.
Constant: VSTR_TYPE_SC_MMAP_FD_ERR_MEM
Constant: VSTR_TYPE_SC_MMAP_FILE_ERR_MEM
Explanation:
This error code means that memory could not be allocated.
Note:
To help the programer unify error paths base->conf->malloc_bad is set
to TRUE, and errno is set to ENOMEM.
Constant: VSTR_TYPE_SC_MMAP_FD_ERR_TOO_LARGE
Constant: VSTR_TYPE_SC_MMAP_FILE_ERR_TOO_LARGE
Explanation:
This error code means that the memory mapping was too big to fit in
the Vstr string (with LFS extensions files are 63 bits, while on a 32
bit computer memory space is still only 32 bits so this isn't a corner
case).
Note:
To help the programer unify error paths errno is set to EFBIG.

set.
Constant: VSTR_TYPE_SC_READ_FILE_ERR_CLOSE_ERRNO
Explanation:
This error code means that the call to close() returned -1, errno is
set.
Note:
Even though this is an error, the readv() has already occurred and
was successful.
If another error occurred (Eg. fstat()/readv()), then any errors from
close() will be hidden.
Constant: VSTR_TYPE_SC_READ_FD_ERR_EOF
Constant: VSTR_TYPE_SC_READ_FILE_ERR_EOF
Explanation:
This error code means that the call to readv() returned 0.
Note:
If you pass 0 as the length to the read_*_file functions, you can
still get the _EOF error if the file is truncated while it is being
read.
To help the programer unify error paths errno is set to ENOSPC.
Constant: VSTR_TYPE_SC_READ_FD_ERR_MEM
Constant: VSTR_TYPE_SC_READ_FILE_ERR_MEM

to TRUE, and errno is set to ENOMEM.
Constant: VSTR_TYPE_SC_READ_FD_ERR_TOO_LARGE
Constant: VSTR_TYPE_SC_READ_FILE_ERR_TOO_LARGE
Explanation:
This error code means that the memory mapping was too big to fit in
the Vstr string (with LFS extensions files are 63 bits, while on a 32
bit computer memory space is still hard limited to 32 bits so this
isn't a corner case).
Note:
To help the programer unify error paths errno is set to EFBIG.

Constants passed to vstr_cntl_base()
Constant: VSTR_CNTL_BASE_GET_CONF
Parameter[1]: Return Vstr configuration
Type[1]: struct Vstr_conf **
Explanation:
This option will get the Vstr configuration for the Vstr string
Constant: VSTR_CNTL_BASE_SET_CONF
Parameter[1]: Vstr configuration
Type[1]: struct Vstr_conf *
Explanation:
This option will set the Vstr configuration for the Vstr string.
Note:
This will only return successfully if either the Vstr string is
empty, or the Vstr configurations have the same value for the
_NUM_BUF_SZ attribute and the new configuration has the same caches
registered. See vstr_swap_cache() for a function that tries to do what
you want.
If the Vstr configuration (Parameter[1]) is NULL, then the default
Vstr configuration will be used.
Constant: VSTR_CNTL_BASE_GET_FLAG_HAVE_CACHE
Parameter[1]: Returns value of flag
Type[1]: int *
Explanation:
This option lets you know if the Vstr string can cache data, this can
only be controlled using the VSTR_CNTL_CONF_GET_FLAG_ALLOC_CACHE flag
before allocation.

Constants passed to vstr_cntl_conf()
Constant: VSTR_CNTL_CONF_GET_NUM_BUF_SZ
Parameter[1]: Returns allocated size of data portion of _BUF nodes
Type[1]: unsigned int *
Explanation:
This option will get the size of the allocated portion of a _BUF type
node.
Note:
The default value of this attribute is currently 48, the reason for
this is that 8 bytes are used for generic node storage and 8 more bytes
are overhead used as in glibc's malloc() implementation. This means
that 64 bytes are allocated for each node of data. Looking at the data
given in the size_cmp spreadsheet and the ex_perf_nodesize example my
guess is that node sizes above 512 probably gain very little, while
consumiung more space.
Constant: VSTR_CNTL_CONF_SET_NUM_BUF_SZ
Parameter[1]: Allocated size of data portion of _BUF nodes
Type[1]: unsigned int
Explanation:
This option will set the size of the allocated portion of a _BUF type
node.
