Function Documentation

FatFilterArchitecture32()

EFI_STATUS FatFilterArchitecture32	(	IN OUT UINT8 **	FileData,
		IN OUT UINT32 *	FileSize )

Moves file pointer and size to point to x86 slice in case FAT Mach-O is used.

Parameters

[in,out]	FileData	Pointer to pointer of the file's data.
[in,out]	FileSize	Pointer to file size of FileData.

Returns

EFI_SUCCESS if no FAT, or a valid 32-bit arch exists.

Definition at line 142 of file MachoFat.c.

FatFilterArchitecture64()

EFI_STATUS FatFilterArchitecture64	(	IN OUT UINT8 **	FileData,
		IN OUT UINT32 *	FileSize )

Moves file pointer and size to point to x86_64 slice in case FAT Mach-O is used.

Parameters

[in,out]	FileData	Pointer to pointer of the file's data.
[in,out]	FileSize	Pointer to file size of FileData.

Returns

EFI_SUCCESS if no FAT, or a valid 64-bit arch exists.

Definition at line 151 of file MachoFat.c.

FatFilterArchitectureByType()

EFI_STATUS FatFilterArchitectureByType	(	IN OUT UINT8 **	FileData,
		IN OUT UINT32 *	FileSize,
		IN MACH_CPU_TYPE	CpuType )

Moves file pointer and size to point to specified slice in case FAT Mach-O is used.

Parameters

[in,out]	FileData	Pointer to pointer of the file's data.
[in,out]	FileSize	Pointer to file size of FileData.
[in]	CpuType	Desired CPU slice to use.

Returns

EFI_SUCCESS if no FAT, or arch was found in valid FAT image.

Definition at line 116 of file MachoFat.c.

FatGetArchitectureOffset()

EFI_STATUS FatGetArchitectureOffset	(	IN CONST UINT8 *	Buffer,
		IN UINT32	BufferSize,
		IN UINT32	FullSize,
		IN MACH_CPU_TYPE	CpuType,
		OUT UINT32 *	FatOffset,
		OUT UINT32 *	FatSize )

Returns offset and size of specified slice in case FAT Mach-O is used. If no FAT is detected, FatOffset and FatSize are set to 0 and FullSize respectively.

Parameters

[in]	Buffer	Pointer to the buffer data.
[in]	BufferSize	Size of Buffer.
[in]	FullSize	Full file size, used to validate sizes within FAT structure.
[in]	CpuType	Desired CPU slice to use.
[out]	FatOffset	Pointer to offset of FAT slice.
[out]	FatSize	Pointer to size of FAT slice.

Returns

EFI_SUCCESS if no FAT, or arch was found in valid FAT image.
