How about

int uncompress_generic(void *src, void *dst, void *buf, int bufsize);

and uncompress_generic can assume that buf can be treated like RAM.
If bufsize is too small, it can return an error. An additional function

int needed_bufsize(void *src);

could be written to compute the minimum buffer size for a given
compressed image.

What do you think?
