Function Documentation

◆ ENTRY_POINT()

int ENTRY_POINT	(	int	argc,
		char **	argv )

Definition at line 198 of file ext4read.c.

◆ Ext4InitialiseUnicodeCollation()

EFI_STATUS Ext4InitialiseUnicodeCollation ( EFI_HANDLE DriverHandle )

Initialises Unicode collation, which is needed for case-insensitive string comparisons within the driver (a good example of an application of this is filename comparison).

Parameters

[in] DriverHandle Handle to the driver image.

Return values

EFI_SUCCESS	Unicode collation was successfully initialised.
!EFI_SUCCESS	Failure.

Definition at line 66 of file ext4read.c.

◆ Ext4StrCmpInsensitive()

INTN Ext4StrCmpInsensitive	(	IN CHAR16 *	Str1,
		IN CHAR16 *	Str2 )

Does a case-insensitive string comparison. Refer to EFI_UNICODE_COLLATION_PROTOCOL's StriColl for more details.

Parameters

[in]	Str1	Pointer to a null terminated string.
[in]	Str2	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.
