/**

Given a Lzma compressed source buffer, this function retrieves the size of
|
||
|
|
the uncompressed buffer and the size of the scratch buffer required
|

|
|
to decompress the compressed source buffer.
|
||
|

|
Retrieves the size of the uncompressed buffer and the temporary scratch buffer
|
||
|
|
required to decompress the buffer specified by Source and SourceSize.
|
||
|
|
The size of the uncompressed buffer is returned in DestinationSize,
|
||
|
|
the size of the scratch buffer is returned in ScratchSize, and RETURN_SUCCESS is returned.
|
||
|
|
This function does not have scratch buffer available to perform a thorough
|

checking of the validity of the source data. It just retrieves the "Original Size"

field from the LZMA_HEADER_SIZE beginning bytes of the source data and output it as DestinationSize.

|
And ScratchSize is specific to the decompression implementation.

|

that will be generated when the compressed buffer specified

by Source and SourceSize is decompressed.

is required to decompress the compressed buffer specified

by Source and SourceSize.
