wcsnlen − determine the length of a fixed-size wide-character string
#include <wchar.h>
size_t wcsnlen(const wchar_t *s, size_t maxlen);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
wcsnlen():
Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
_GNU_SOURCE
The wcsnlen() function is the wide-character equivalent of the strnlen(3) function. It returns the number of wide-characters in the string pointed to by s, not including the terminating L'\0' character, but at most maxlen. In doing this, wcsnlen() looks only at the first maxlen wide-characters at s and never beyond s+maxlen.
The wcsnlen() function returns wcslen(s), if that is less than maxlen, or maxlen if there is no L'\0' character among the first maxlen wide characters pointed to by s.
The wcsnlen() function is provided in glibc since version 2.1.
This function is a GNU extension.
