wmemchr

Defined in header <wchar.h> 
wchar_t *wmemchr( const wchar_t *ptr, wchar_t ch, size_t count );
-		 (1) (since C95) 
/*QWchar_t*/ *wmemchr( /*Qwchar_t*/ *ptr, wchar_t ch, size_t count );
-		 (2) (since C23)
-1) Locates the first occurrence of wide character ch in the initial count wide characters of the wide character array or integer array of compatible type, pointed to by ptr.
-2) Type-generic function equivalent to (1). Let T be an unqualified wide character object type. If a macro definition of each of these generic functions is suppressed to access an actual function (e.g. if (wmemchr) or a function pointer is used), the actual function declaration (1) becomes visible.

If count is zero, the function returns a null pointer.

Parameters

- - - -
ptr - pointer to the wide character array to be examined
ch - wide character to search for
count - number of wide characters to examine

Return value

Pointer to the location of the wide character, or a null pointer if no such character is found.

Example

#include <locale.h>
-#include <stdio.h>
-#include <wchar.h>
- 
-int main(void)
-{
-    wchar_t str[] = L"诺不轻信，故人不负我\0诺不轻许，故我不负人。";
-    size_t sz = sizeof str / sizeof *str;
- 
-    wchar_t target = L'许';
-    wchar_t* result = wmemchr(str, target, sz);
- 
-    if (result)
-    {
-        setlocale(LC_ALL, "en_US.utf8");
-        printf("Found '%lc' at position %td\n",target, result - str);
-    }
-}

Possible output:

-
Found '许' at position 14
