ISRUNE(3)             DragonFly Library Functions Manual             ISRUNE(3)

NAME
     isrune, isrune_l -- valid character test

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     isrune(int c);

     #include <xlocale.h>

     int
     isrune_l(int c, locale_t locale);

DESCRIPTION
     The isrune() and isrune_l() functions test for any character that is
     valid in the current character set.  In the ASCII character set, this is
     equivalent to isascii().

     The _l-suffixed version takes an explicit locale argument, whereas the
     non-suffixed version uses the current global or per-thread locale.

RETURN VALUES
     The isrune() and isrune_l() functions return zero if the character tests
     false and returns non-zero if the character tests true.

SEE ALSO
     ctype(3), ctype_l(3), isascii(3), iswrune(3), xlocale(3), ascii(7)

HISTORY
     The isrune() function appeared in 4.4BSD.
