wcsrchr

Defined in header <wchar.h> 
wchar_t *wcsrchr( const wchar_t *str, wchar_t ch );
+		 (1) (since C95) 
/*QWchar_t*/ *wcsrchr( /*QWchar_t*/ *str, wchar_t ch );
+		 (2) (since C23)
+1) Finds the last occurrence of the wide character ch in the wide string pointed to by str.
+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 (wcsrchr) or a function pointer is used), the actual function declaration (1) becomes visible.

Parameters

+ + +
str - pointer to the null-terminated wide string to be analyzed
ch - wide character to search for

Return value

Pointer to the found character in str, 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 arr[] = L"白猫 黒猫 кошки";
+    wchar_t *cat = wcsrchr(arr, L'猫');
+    wchar_t *dog = wcsrchr(arr, L'犬');
+ 
+    setlocale(LC_ALL, "en_US.utf8");
+ 
+    cat ? printf("The character 猫 found at position %td\n", cat - arr)
+        : puts("The character 猫 not found");
+ 
+    dog ? printf("The character 犬 found at position %td\n", dog - arr)
+        : puts("The character 犬 not found");
+}

Output:

+
The character 猫 found at position 4
+The character 犬 not found
