+  * @description:
+  *   Decompress a zipped input buffer into an output buffer.  This function
+  *   is modeled after zlib's `uncompress' function.
+  *
+  * @input:
+  *   memory ::
+  *     A FreeType memory handle.
+  *
+  *   input ::
+  *     The input buffer.
+  *
+  *   input_len ::
+  *     The length of the input buffer.
+  *
+  * @output:
+  *   output::
+  *     The output buffer.
+  *
+  * @inout:
+  *   output_len ::
+  *     Before calling the function, this is the the total size of the
+  *     output buffer, which must be large enough to hold the entire
+  *     uncompressed data (so the size of the uncompressed data must be
+  *     known in advance).  After calling the function, `output_len' is the
+  *     size of the used data in `output'.
+  *
+  * @return:
+  *   FreeType error code.  0~means success.
+  *
+  * @note:
+  *   This function may return `FT_Err_Unimplemented_Feature' if your build
+  *   of FreeType was not compiled with zlib support.
