* The function will provide a pointer to a fully allocated and initialized LZ4F_decompressionContext_t object.
* The result is an errorCode, which can be tested using LZ4F_isError().
* dctx memory can be released using LZ4F_freeDecompressionContext();
* The result of LZ4F_freeDecompressionContext() is indicative of the current state of decompressionContext when being released.
* That is, it should be == 0 if decompression has been completed fully and correctly.
