+ * If the compressed data would be larger than DST_NBYTES the function should
+ * return a value greater than or equal to DST_NBYTES. On failure the

+ *
+ * The uncompression function is the inverse of compression and takes the
+ * same arguments. The SRC_NBYTES argument is the number of compressed bytes
+ * in SRC. The function should uncompress SRC into DST. For redundancy,
+ * DST_NBYTES contains the size of the DST buffer although if the algorithm
+ * is operating properly and the file has not been corrupted the uncompressed
+ * data will never be larger than DST_NBYTES. The function should return the
+ * number of bytes in the DST buffer or zero on failure. Failure includes
