FUNCTION

	<>---case-insensitive wide character string compare

INDEX

	wcscasecmp

ANSI_SYNOPSIS

	#include 

	int wcscasecmp(const wchar_t *<[a]>, const wchar_t *<[b]>);

TRAD_SYNOPSIS

	#include 

	int wcscasecmp(<[a]>, <[b]>)

	wchar_t *<[a]>;

	wchar_t *<[b]>;

DESCRIPTION

	<> compares the wide character string at <[a]> to

	the wide character string at <[b]> in a case-insensitive manner.

RETURNS

	If <<*<[a]>>> sorts lexicographically after <<*<[b]>>> (after

	both are converted to uppercase), <> returns a

	number greater than zero.  If the two strings match,

	<> returns zero.  If <<*<[a]>>> sorts

	lexicographically before <<*<[b]>>>, <> returns a

	number less than zero.

PORTABILITY

POSIX-1.2008

<> requires no supporting OS subroutines. It uses

tolower() from elsewhere in this library.
