The DECOMPRESSDATA structure provides decompression to the L_DecompressBuffer function.
If pBuffer does not point to a full tile or strip, set uFlags to DECOMPRESS_STRIP_START when the tile/strip begins and set it to DECOPMRESS_STRIP_END when the tile/strip ends.
Some functions which take this structure as a parameter require that the structure be initialized prior to the function call. You must set the uStructSize member to the total size, in bytes, of the structure. Use the sizeof() operator to calculate this value. Functions that do not require the structure be initialized will take the total size of the structure, in bytes, as an additional function parameter.
