MRCI API Error/Return Codes
The Microsoft Real-time Compression Interface (MRCI API) functions may
return the following error codes:
0000H MRCI_NO_ERR fn was successful
0001H MRCI_ERR_NOT_SUPPORTED Unsupported fn number in AX
0002H MRCI_ERR_BUSY MRCI support is busy. This could happen,
for instance, if a background task such as
SmartDrv is using MRCI support. Just try
the operation again.
0003H MRCI_ERR_BUF_OVERFLOW Destination buffer too small
0004H MRCI_ERR_INCOMPRESSIBLE Source data could not be compressed (MRCI
returns this if it sees that compressing the
data will not save at least one wChunkLen
unit of data (see MRCRequestRec).
When this error is returned, the content of
the destination buffer is undefined.
0005H MRCI_ERR_BAD_FORMAT Compressed data is in unrecognized format.
This is returned when the source contains
uncompressed data with no recognizable MRCI
header. It may occur on a source buffer
overrun; but that is not guaranteed by the
