int ispunct(int c);
Implemented
IEEE Std 1003.1-2017
The ispunct() function shall test whether c is a character of class punct in the current locale.
The c argument is an int, the value of which the application shall ensure is a character representable as an
unsigned char or equal to the value of the macro EOF. If the argument has any other value, the behavior is
undefined.
The ispunct() function shall return non-zero if c is a punctuation character, otherwise shall return 0.
No errors are defined.
