ISSPACE(3)						   BSD 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:

     ``	''   ``
''	``v''	  ``f''    ``
''    `` ''

     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'').
