EngFatToStr()

VOID EFIAPI EngFatToStr	(	IN EFI_UNICODE_COLLATION_PROTOCOL *	This,
		IN UINTN	FatSize,
		IN CHAR8 *	Fat,
		OUT CHAR16 *	String )

Converts an 8.3 FAT file name in an OEM character set to a Null-terminated string.

Parameters

This	Protocol instance pointer.
FatSize	The size of the string Fat in bytes.
Fat	A pointer to a Null-terminated string that contains an 8.3 file name using an 8-bit OEM character set.
String	A pointer to a Null-terminated string. The string must be preallocated to hold FatSize characters.

EngMetaiMatch()

BOOLEAN EFIAPI EngMetaiMatch	(	IN EFI_UNICODE_COLLATION_PROTOCOL *	This,
		IN CHAR16 *	String,
		IN CHAR16 *	Pattern )

Performs a case-insensitive comparison of a Null-terminated pattern string and a Null-terminated string.

Parameters

This	Protocol instance pointer.
String	A pointer to a Null-terminated string.
Pattern	A pointer to a Null-terminated pattern string.

Return values

TRUE	Pattern was found in String.
FALSE	Pattern was not found in String.

EngStriColl()

INTN EFIAPI EngStriColl	(	IN EFI_UNICODE_COLLATION_PROTOCOL *	This,
		IN CHAR16 *	Str1,
		IN CHAR16 *	Str2 )

Performs a case-insensitive comparison of two Null-terminated strings.

Parameters

This	Protocol instance pointer.
Str1	A pointer to a Null-terminated string.
Str2	A pointer to a Null-terminated string.

Return values

0	Str1 is equivalent to Str2
>	0 Str1 is lexically greater than Str2
<	0 Str1 is lexically less than Str2

EngStrLwr()

VOID EFIAPI EngStrLwr	(	IN EFI_UNICODE_COLLATION_PROTOCOL *	This,
		IN OUT CHAR16 *	Str )

Converts all the characters in a Null-terminated string to lower case characters.

Parameters

This	Protocol instance pointer.
Str	A pointer to a Null-terminated string.

EngStrToFat()

BOOLEAN EFIAPI EngStrToFat	(	IN EFI_UNICODE_COLLATION_PROTOCOL *	This,
		IN CHAR16 *	String,
		IN UINTN	FatSize,
		OUT CHAR8 *	Fat )

Converts a Null-terminated string to legal characters in a FAT filename using an OEM character set.

Parameters

This	Protocol instance pointer.
String	A pointer to a Null-terminated string. The string must be preallocated to hold FatSize characters.
FatSize	The size of the string Fat in bytes.
Fat	A pointer to a Null-terminated string that contains an 8.3 file name using an OEM character set.

Return values

TRUE	Fat is a Long File Name
FALSE	Fat is an 8.3 file name

EngStrUpr()

VOID EFIAPI EngStrUpr	(	IN EFI_UNICODE_COLLATION_PROTOCOL *	This,
		IN OUT CHAR16 *	Str )

Converts all the characters in a Null-terminated string to upper case characters.

Parameters

This	Protocol instance pointer.
Str	A pointer to a Null-terminated string.
