iissaasscciiii() -- ctype Function (libc)

Check if a character is an ASCII character
#iinncclluuddee <ccttyyppee.hh>
iinntt iissaasscciiii(_c) iinntt _c;

iissaasscciiii()  tests whether  _c is  an ASCII  character (0 <=  _c <=  0177).  It
returns a number other than zero if _c is an ASCII character, and zero if it
is not.  Many ccttyyppee macros fail if passed a non-ASCII value other than EOF.
