проверка знаков препинания (test for a punctuation character)

Пролог (Prolog)

This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

Имя (Name)

ispunct, ispunct_l — test for a punctuation character

Синопсис (Synopsis)

#include <ctype.h>

int ispunct(int c); int ispunct_l(int c, locale_t locale);


Описание (Description)

For ispunct(): The functionality described on this reference page
       is aligned with the ISO C standard. Any conflict between the
       requirements described here and the ISO C standard is
       unintentional. This volume of POSIX.1‐2017 defers to the ISO C
       standard.

The ispunct() and ispunct_l() functions shall test whether c is a character of class punct in the current locale, or in the locale represented by locale, respectively; see the Base Definitions volume of POSIX.1‐2017, 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.

The behavior is undefined if the locale argument to ispunct_l() is the special locale object LC_GLOBAL_LOCALE or is not a valid locale object handle.


Возвращаемое значение (Return value)

The ispunct() and ispunct_l() functions shall return non-zero if
       c is a punctuation character; otherwise, they shall return 0.

Использование в приложениях (Application usage)

To ensure applications portability, especially across natural
       languages, only these functions and the functions in the
       reference pages listed in the SEE ALSO section should be used for
       character classification.
