iissppuunncctt() -- ctype Function (libc)

Check if a character is a punctuation mark
#iinncclluuddee <ccttyyppee.hh>
iinntt iissppuunncctt(_c) iinntt _c;

iissppuunncctt() tests whether the argument _c is a punctuation mark, i.e., neither
an alphanumeric  character nor  a control  character.  It returns  a number
other than zero if the character  tested is a punctuation mark, and zero if
it is not.  iissppuunncctt() assumes that _c is an ASCII character or EEOOFF.
