wcsncasecmp
is the wide-character equivalent of
strncasecmp
. It compares the wide-character string
s1 and the wide-character string
s2, but at most n wide
characters from each string, ignoring case differences (towupper, towlower).
wcscasecmp
returns 0
if the wide-character strings 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.
