| 823 | Decompresses a compressed source buffer.\r | |
| 824 | \r | |
| 825 | The Decompress() function extracts decompressed data to its original form.\r | |
| 826 | This protocol is designed so that the decompression algorithm can be\r | |
| 827 | implemented without using any memory services. As a result, the Decompress()\r | |
| 828 | Function is not allowed to call AllocatePool() or AllocatePages() in its\r | |
| db405d1b | 829 | implementation. It is the caller's responsibility to allocate and free the\r |
| 162ed594 | 830 | Destination and Scratch buffers.\r |
| 831 | If the compressed source data specified by Source and SourceSize is\r | |
| 832 | sucessfully decompressed into Destination, then EFI_SUCCESS is returned. If\r | |
| 833 | the compressed source data specified by Source and SourceSize is not in a\r | |
| 834 | valid compressed data format, then EFI_INVALID_PARAMETER is returned.\r | |
| 835 | \r | |
| 836 | @param This A pointer to the EFI_DECOMPRESS_PROTOCOL instance.\r | |

| 839 | @param Destination On output, the destination buffer that contains\r | |
| 840 | the uncompressed data.\r | |
| 841 | @param DestinationSize The size of the destination buffer. The size of\r | |
| 842 | the destination buffer needed is obtained from\r | |
| 843 | EFI_DECOMPRESS_PROTOCOL.GetInfo().\r | |
| 844 | @param Scratch A temporary scratch buffer that is used to perform\r | |
| 845 | the decompression.\r | |
| 846 | @param ScratchSize The size of scratch buffer. The size of the\r | |
| 847 | scratch buffer needed is obtained from GetInfo().\r | |
