ispunct - test for a punctuation character SYNOPSIS
#include <ctype.h> int ispunct(int c); DESCRIPTION
The ispunct() function shall test whether c is a character of class punct in the program's current locale; see the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, 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. RETURN VALUE
The ispunct() function shall return non-zero if c is a punctuation character; otherwise, it shall return 0. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
To ensure applications portability, especially across natural languages, only this function and those listed in the SEE ALSO section should be used for character classification. RATIONALE
None. FUTURE DIRECTIONS
None. SEE ALSO

isgraph - test for a visible character SYNOPSIS
#include <ctype.h> int isgraph(int c); DESCRIPTION
The isgraph() function shall test whether c is a character of class graph in the program's current locale; see the Base Definitions volume of IEEE Std 1003.1-2001, Chapter 7, 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. RETURN VALUE
The isgraph() function shall return non-zero if c is a character with a visible representation; otherwise, it shall return 0. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
