wcslen, wcsnlen_s

Defined in header <wchar.h> 
size_t wcslen( const wchar_t *str );
-		 (1) (since C95) 
size_t wcsnlen_s(const wchar_t *str, size_t strsz);
-		 (2) (since C11)
-1) Returns the length of a wide string, that is the number of non-null wide characters that precede the terminating null wide character.
-2) Same as (1), except that the function returns zero if str is a null pointer and returns strsz if the null wide character was not found in the first strsz wide characters of src As with all bounds-checked functions, wcslen_s only guaranteed to be available if __STDC_LIB_EXT1__ is defined by the implementation and if the user defines __STDC_WANT_LIB_EXT1__ to the integer constant 1 before including <stdio.h>..

Parameters

- - -
str - pointer to the null-terminated wide string to be examined
strsz - maximum number of wide characters to examine

Return value

-1) The length of the null-terminated wide string str.
-2) The length of the null-terminated wide string str on success, zero if str is a null pointer, strsz if the null wide character was not found.

Notes

strnlen_s and wcsnlen_s are the only bounds-checked functions that do not invoke the runtime constraints handler. They are pure utility functions used to provide limited support for non-null terminated strings.

Example

#include <wchar.h>
-#include <stdio.h>
- 
-int main(void)
-{
-    wchar_t str[] = L"How many wide characters does this string contain?";
- 
-    printf("without null character: %zu\n", wcslen(str));
-    printf("with null character: %zu\n", sizeof str / sizeof *str);
-}

Output:

-
without null character: 50
-with null character: 51
