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.
