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 standard white-space characters for which isalnum(3) is
     false.  The standard white-space characters are the following:

	   ' '	  Space character.
	   \f	  Form feed.
	   \n	  New-line.
	   \r	  Carriage return.
	   \t	  Horizontal tab.
	   \v	  And vertical tab.

     In the ``C'' locale, isspace() returns true only for the standard white-space characters.

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

     toascii(3), tolower(3), toupper(3), ascii(7)

STANDARDS
     The isspace() function conforms to ANSI X3.159-1989 (``ANSI C89'').

CAVEATS
     The argument to isspace() must be EOF or representable as an unsigned char; otherwise, the
     behavior is undefined.  See the CAVEATS section of ctype(3) for more details.
