wcslen(), wcsnlen()

compute length of wide character string 

Function


SYNOPSIS

#include <wchar.h>

size_t wcslen(const wchar_t *ws);

size_t wcsnlen(const wchar_t *ws, size_t maxlen);


DESCRIPTION

The wcslen() function determines the length of the wide character string pointed to by ws not including the terminating NULL character. The wcsnlen() function computes the length of ws, but never scans beyond the first maxlen wide characters of ws.


PARAMETERS

ws 

Is a null-terminated string.

maxlen 

The maximum number of wide characters to scan for the end of wide string marker before returning.


RETURN VALUES

The wcslen() function returns the number of characters in the string pointed to by ws excluding the terminal NULL. The wcsnlen() function returns either the same result as wcslen() or maxlen, whichever is smaller.


CONFORMANCE
