in the boot services environment to perform lexical comparison functions on Unicode strings for
given languages.

Summary
Is used to perform case-insensitive comparisons of Unicode strings.

Protocol Interface Structure
typedef struct {
EFI_UNICODE_COLLATION_STRICOLL StriColl;
EFI_UNICODE_COLLATION_METAIMATCH MetaiMatch;
EFI_UNICODE_COLLATION_STRLWR StrLwr;
EFI_UNICODE_COLLATION_STRUPR StrUpr;
EFI_UNICODE_COLLATION_FATTOSTR FatToStr;
EFI_UNICODE_COLLATION_STRTOFAT StrToFat;
CHAR8 *SupportedLanguages;
} UNICODE_COLLATION_INTERFACE;
Parameters
StriColl Performs a case-insensitive comparison of two Null-terminated
Unicode strings. See the StriColl()
function description.
MetaiMatch Performs a case-insensitive comparison between a Null-
terminated Unicode pattern string and a Null-terminated Unicode
string. The pattern string can use the ‘?’ wildcard to match any
character, and the ‘*’ wildcard to match any substring. See the
MetaiMatch()
function description.
StrLwr Converts all the Unicode characters in a Null-terminated
Unicode string to lowercase Unicode characters. See the
StrLwr()
function description.
StrUpr Converts all the Unicode characters in a Null-terminated
Unicode string to uppercase Unicode characters. See the
StrUpr()
function description.
FatToStr Converts an 8.3 FAT file name using an OEM character set to a
Null-terminated Unicode string. See the FatToStr()
function
description.
