[Module configuration]

The decompression library function has a hierarchical module structure in terms of functionality. The high-level functions are easy to use because they are decompressed by interpreting the compression algorithm and parameters, but have the disadvantage of being linked with extra object code.
∙ If you want to link only the minimum necessary object code, you can use a low-level function. In this case, be careful not to make any difference from the operation on the compression tool side.
The following figure shows the extension library module configuration.
