typedef EFI_STATUS(EFIAPI * EFI_PEI_DECOMPRESS_DECOMPRESS)(IN CONST EFI_PEI_DECOMPRESS_PPI *This, IN CONST EFI_COMPRESSION_SECTION *InputSection, OUT VOID **OutputBuffer, OUT UINTN *OutputSize)

Decompress a single compression section in a firmware file.

Decompresses the data in a compressed section and returns it as a series of standard PI Firmware File Sections. The required memory is allocated from permanent memory.

Parameters:
This Points to this instance of the EFI_PEI_DECOMPRESS_PEI PPI.
InputSection Points to the compressed section.
OutputBuffer Holds the returned pointer to the decompressed sections.
OutputSize Holds the returned size of the decompress section streams.
Return values:
EFI_SUCCESS The section was decompressed successfully. OutputBuffer contains the resulting data and OutputSize contains the resulting size.
EFI_OUT_OF_RESOURCES Unable to allocate sufficient memory to hold the decompressed data.
EFI_UNSUPPORTED The compression type specified in the compression header is unsupported.
