-Subject: [PATCH] Change th_get_size() macro to return unsigned int
-
-On systems where size_t is larger than an int (and larger than
-unsigned int), then in various places in the library, where
-stuff like this happens:
-
- size_t sz = th_get_size(t);
-
-then the int value returned from th_get_size() is sign extended to
-some unwieldy amount.
-
-On 64bit systems, this can yield extremely large values.
-
-By fixing this problem in the header, and only for th_get_size(),
-we avoid breaking the API of the function call oct_to_int()
-(which arguably should return an unsigned int, since the sscanf()
-it uses expects to yield an unsigned int). We also fix the library,
-which uses th_get_size() internally to assign sizes to size_t.
-
-The drawback is that not all client code that uses th_get_size()
-will be fixed, until they recompile, but they will automatically
-take advantage of the bugs fixed *inside* the library.
-
-The remaining th_get_*() functions operate on modes and CRC values
-and the like, and should be fine, remaining as ints.
-
-Thanks very much to Magnus Holmgren for catching this behaviour.
