DESCRIPTION
The wcsncasecmp() function
is the wide-character equivalent of the strncasecmp(3) function. It
compares the wide-character string pointed to by s1 and the wide-character
string pointed to by s2, but at most n wide characters from each
string, ignoring case differences (towupper(3), towlower(3)).
RETURN VALUE
The wcsncasecmp() function
returns zero if the wide-character strings at s1 and s2, truncated to at most length
n, are equal except
for case distinctions. It returns a positive integer if
truncated s1 is
greater than truncated s2, ignoring case. It returns a
negative integer if truncated s1 is smaller than truncated
s2, ignoring
case.
