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);

DESCRIPTION
     The isspace() function tests for the white-space characters.  For any lo-
     cale, 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 ar-
     gument is representable as	an unsigned char or the	value of EOF.

RETURN VALUES
     The isspace() function returns zero if the	character tests	false and re-
     turns non-zero if the character tests true.

COMPATIBILITY
     Although isspace()	accepts	arguments outside of the range of the unsigned
     char type in locales with large character sets, this is a 4.4BSD exten-
     sion and the iswspace() function should be	used instead for maximum
     portability.

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

STANDARDS
     The isspace() function conforms to	ISO/IEC	9899:1990 ("ISO	C90").
