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:

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

     In the "C" locale, isspace() successful test is limited to these characters only.	The value of the argument must be 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), isalnum_l(3), iswspace(3), multibyte(3), ascii(7)

STANDARDS

     The isspace() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
