wcslen, wcsnlen
— get length of wide-character string
#include

size_t
wcslen(const wchar_t
*string);
size_t
wcsnlen(const wchar_t *string,
size_t maxlen);
The
wcslen()
and wcsnlen() functions count the number of
wide-characters that are present in string. They stop
counting when they encounter a null wide-character. The terminating null
wide-character is not included in the count.
Additionally,
wcsnlen()
stops counting after it has counted maxlen
wide-characters.
The
wcslen()
and wcsnlen() functions are the wide-character
equivalents of strlen(3C) and
strnlen(3C), respectively.
The wcslen() function returns the length
of string. The wcsnlen()
function returns the smaller of the length of string
and maxlen.

The wcslen() function was introduced in
X/Open Portability Guide Issue 4
(“XPG4”) and standardized in ISO/IEC
9899:1999 (“ISO C99”). The
wcsnlen() function was introduced in
IEEE Std 1003.1-2008 (“POSIX.1”).
