As all is<xxx> functions it takes an *int* or *unsigned char* !

man isspace

NAME
       isalnum,  isalpha,  isascii,  isblank,  iscntrl,  isdigit,
       isgraph,  islower,  isprint,  ispunct,  isspace,  isupper,
       isxdigit - character classification routines

SYNOPSIS
       #include <ctype.h>

       int isalnum (int c);
       int isalpha (int c);
       int isascii (int c);
       int isblank (int c);
       int iscntrl (int c);
       int isdigit (int c);
       int isgraph (int c);
       int islower (int c);
       int isprint (int c);
       int ispunct (int c);
       int isspace (int c);
       int isupper (int c);
       int isxdigit (int c);

DESCRIPTION
       These functions check whether c, which must have the value
       of an unsigned char or EOF, falls into a certain character
       class according to the current locale.

Bye.
Michael.
