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 single C chars locales the value of the argument is representable as
     an unsigned char or the value of EOF.  In the ASCII character set, this
     includes the following characters (with their numeric values shown in
     octal):

     011 ht	   012 nl	 013 vt        014 np	     015 cr
     040 sp

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

SEE ALSO
     ctype(3), ascii(7)

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