UNICODE_COLLATION.StriColl()
Summary
Performs a case-insensitive comparison of two Null-terminated Unicode strings.
Prototype
INTN
(EFIAPI *EFI_UNICODE_COLLATION_STRICOLL) (
IN UNICODE_COLLATION_INTERFACE *This,
IN CHAR16 *s1,
IN CHAR16 *s2
);
Parameters
This A pointer to the UNICODE_COLLATION_INTERFACE
instance. Type UNICODE_COLLATION_INTERFACE is
defined in Section 11.7.
s1 A pointer to a Null-terminated Unicode string.
s2 A pointer to a Null-terminated Unicode string.
Description
The StriColl() function performs a case-insensitive comparison of two Null-terminated
Unicode strings.
This function performs a case-insensitive comparison between the Unicode string s1 and the
Unicode string s2 using the rules for the language codes that this protocol instance supports. If s1
is equivalent to s2, then 0 is returned. If s1 is lexically less than s2, then a negative number will
be returned. If s1 is lexically greater than s2, then a positive number will be returned. This
function allows Unicode strings to be compared and sorted.
Status Codes Returned
0 s1 is equivalent to s2.
> 0 s1 is lexically greater than s2.
< 0 s1 is lexically less than s2.
