ispunct - test for punctuation character

Syntax

#include <ctype.h> int ispunct(int c);

Description ispunct() tests whether c is a punctuation character, i.e. not a control, alphanumeric, or

	white-space character (see isspace). In all cases, the argument c is an int, the value of which must be representable as an unsigned char or must equal the value of the macro EOF. If the argument c has any other value, the behavior is undefined.
Return val.	!= 0 0	Punctuation character Not a punctuation character
Notes	ispunct() is implemented both as a function and as a macro. To generate a function call, the definition of the macro name must be first undefined (#undef ispunct). The behavior of ispunct() is determined by the class punct of the current locale. The current locale is the C locale, unless it was explicitly changed using setlocale().
