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 Laq\0aq character, but at most
maxlen.
In doing this,
wcsnlen()
looks only at the first maxlen
wide-characters at s and never beyond s+maxlen.
RETURN VALUE
The
wcsnlen()
function returns wcslen(s), if that is less than
maxlen, or maxlen if there is no Laq\0aq character among the
first maxlen wide characters pointed to by s.
