12 *len     - len of pre-read data in inbuf
13 *fill    - function to fill inbuf when empty
14 *flush   - function to write out outbuf
15 *outbuf  - output buffer
16 *posp    - if non-null, input position (number of bytes read) will be
17 *	  returned here
18 *
19 *If len != 0, inbuf should contain all the necessary input data, and fill
20 *should be NULL
21 *If len = 0, inbuf can be NULL, in which case the decompressor will allocate
22 *the input buffer.  If inbuf != NULL it must be at least XXX_IOBUF_SIZE bytes.
23 *fill will be called (repeatedly...) to read data, at most XXX_IOBUF_SIZE
24 *bytes should be read per call.  Replace XXX with the appropriate decompressor
25 *name, i.e. LZMA_IOBUF_SIZE.
26 *
27 *If flush = NULL, outbuf must be large enough to buffer all the expected
28 *output.  If flush != NULL, the output buffer will be allocated by the
29 *decompressor (outbuf = NULL), and the flush function will be called to
30 *flush the output buffer at the appropriate time (decompressor and stream
31 *dependent).
