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);

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

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

     In	the "C"	locale isspace() successful test is limited to this characters
     only.  For	single C chars locales (see multibyte(3)) the value of the
     argument is representable as an unsigned char or the value	of EOF.

RETURN VALUES
     The isspace() function returns zero if the	character tests	false and
     returns 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'').
