NAME
       buffer_getline_sa - read line from buffer

SYNTAX
       #include <stralloc.h>
       #include <buffer.h>

       int buffer_getline_sa(buffer* b,stralloc* sa);

DESCRIPTION
       buffer_getline_sa appends data from the b to sa until a '\n' is found,
       NOT overwriting the previous content of sa.  The new-line is also
       appended to sa.

       If reading from the buffer or allocating memory fails,
       buffer_getline_sa returns -1 and sets errno appropriately.  At that
       point sa may be empty or it may already contain a partial token.

RETURN VALUE
       -1 on error (setting errno), 0 on EOF, 1 when successful.

RATIONALE
       buffer_getline_sa appends instead of overwriting so it can be used on
       non-blocking sockets (these signal error and set errno to EAGAIN; in
       this case you can simply call buffer_getline_sa again when select or
       poll indicate more data is available).
