WMEMCHR(3P)             POSIX Programmer's Manual            WMEMCHR(3P)

ПРОЛОГ

       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

       wmemchr — find a wide character in memory

СИНТАКСИС

       #include <wchar.h>

       wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);

ОПИСАНИЕ

       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 wmemchr() function shall locate the first occurrence of wc in
       the initial n wide characters of the object pointed to by ws.
       This function shall not be affected by locale and all wchar_t
       values shall be treated identically. The null wide character and
       wchar_t values not corresponding to valid characters shall not be
       treated specially.

       If n is zero, the application shall ensure that ws is a valid
       pointer and the function behaves as if no valid occurrence of wc
       is found.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       The wmemchr() function shall return a pointer to the located wide
       character, or a null pointer if the wide character does not occur
       in the object.
