wcsnlen — determine the length of a fixed-size wide-character string
#define _GNU_SOURCE #include <wchar.h>
size_t wcsnlen( |
const wchar_t *s, |
size_t maxlen); |
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.
