Имя (Name)
wmemchr — find a wide character in memory
Синопсис (Synopsis)
#include <wchar.h>
wchar_t *wmemchr(const wchar_t *ws, wchar_t wc, size_t n);
Описание (Description)
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.
Возвращаемое значение (Return value)
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.
