ISSPACE(3)	       FreeBSD Library Functions Manual		    ISSPACE(3)

NAME
     isspace --	white-space character test

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <ctype.h>

     int
     isspace(int c);

     int
     isspace_l(int c, locale_t loc);

DESCRIPTION
     The isspace() function tests for white-space characters.  For any locale,
     this includes the following standard characters:

     ``\t''   ``\n''	``\v''	  ``\f''    ``\r''    `` ''

     In	the "C"	locale,	isspace() returns non-zero for these characters	only.
     The value of the argument must be representable as	an unsigned char or
     the value of EOF.

     The isspace_l() function takes an explicit	locale argument, whereas the
     isspace() function	uses the current global	or per-thread locale.

RETURN VALUES
     The isspace() and isspace_l() functions return zero if the	character
     tests false and return non-zero if	the character tests true.

COMPATIBILITY
     The 4.4BSD	extension of accepting arguments outside of the	range of the
     unsigned char type	in locales with	large character	sets is	considered
     obsolete and may not be supported in future releases.  The	iswspace()
     function should be	used instead.

SEE ALSO
     ctype(3), iswspace(3), multibyte(3), ascii(7)

STANDARDS
     The isspace() function conforms to	ISO/IEC	9899:1990 (``ISO C90'').  The
     isspace_l() function conforms to IEEE Std 1003.1-2008 (``POSIX.1'').
