Notifies a video decompression driver to decompress a frame of data into an application-supplied buffer.

wParam
Address of an ICDECOMPRESS structure.
lParam
Size, in bytes, of the ICDECOMPRESS structure.

If you want the driver to decompress data directly to the screen, send the ICM_DRAW message.

The driver returns an error if this message is received before the ICM_DECOMPRESS_BEGIN message.
