| 67 | \r |
| 68 | Arguments:\r |
| 69 | \r |
| 70 | SrcBuffer - The buffer storing the source data\r |
| 71 | SrcSize - The size of source data\r |
| 72 | DstBuffer - The buffer to store the compressed data\r |
| 73 | DstSize - On input, the size of DstBuffer; On output,\r |
| 74 | the size of the actual compressed data.\r |
| 75 | \r |
| 76 | Returns:\r |
| 77 | \r |
| 78 | EFI_BUFFER_TOO_SMALL - The DstBuffer is too small. In this case,\r |
| 79 | DstSize contains the size needed.\r |
| 80 | EFI_SUCCESS - Compression is successful.\r |
| 30f80dd8 |
81 | EFI_OUT_OF_RESOURCES - No resource to complete function.\r |
| 82 | EFI_INVALID_PARAMETER - Parameter supplied is wrong.\r |
