iissssppaaccee() -- ctype Function (libc)

Check if a character prints white space
#iinncclluuddee <ccttyyppee.hh>
iinntt iissssppaaccee(_c) iinntt _c;

iissssppaaccee() 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.  iissssppaaccee() assumes that
_c is an ASCII character or EOF.
