isspace() -- ctype Function (libc)

Check if a character prints white space
#include <ctype.h>
int isspace(c) int c;

isspace() tests  whether the argument c is a  space, tab, newline, carriage
return, or form-feed  character.  It returns a number other  than zero if c
is a white-space character, and zero  if it is not.  isspace() assumes that
c is an ASCII character or EOF.

Example

For an example of how to use this macro, see the entry for ctype.h.
