+/*++
+
+Routine Description:
+
+  The compression routine.
+
+Arguments:
+
+  SrcBuffer   - The buffer storing the source data
+  SrcSize     - The size of source data
+  DstBuffer   - The buffer to store the compressed data
+  DstSize     - On input, the size of DstBuffer; On output,
+                the size of the actual compressed data.
+
+Returns:
+
+  EFI_BUFFER_TOO_SMALL  - The DstBuffer is too small. In this case,
+                DstSize contains the size needed.
+  EFI_SUCCESS           - Compression is successful.
+  EFI_OUT_OF_RESOURCES  - No resource to complete function.
+  EFI_INVALID_PARAMETER - Parameter supplied is wrong.
