Имя (Name)
wcschr — wide-character string scanning operation
Синопсис (Synopsis)
#include <wchar.h>
wchar_t *wcschr(const wchar_t *ws, wchar_t wc);
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 wcschr() function shall locate the first occurrence of wc in
the wide-character string pointed to by ws. The application
shall ensure that the value of wc is a character representable as
a type wchar_t and a wide-character code corresponding to a valid
character in the current locale. The terminating null wide-
character code is considered to be part of the wide-character
string.
Возвращаемое значение (Return value)
Upon completion, wcschr() shall return a pointer to the wide-
character code, or a null pointer if the wide-character code is
not found.
