get_filename - Returns a pointer to the filename portion of a path. Allegro game
char *get_filename(const char *path);
Finds out the filename portion of a completely specified file path. Both `\' and
`/' are recognized as directory separators under DOS and Windows. However,
only `/' is recognized as directory separator under other platforms. Example:
allegro_message("Running `%s'\n", get_filename(name));
Note that Allegro won't perform any IO operations during the verification. This
means that if you have `/a/path/like/this/', which doesn't have a filename,
the function will return a pointer to the trailing null character. However, if
you have `/a/path/like/this', Allegro will return a pointer to `this', even if
it is a valid directory.
Returns a pointer to the portion of `path' where the filename starts, or the
beginning of `path' if no valid filename is found (eg. you are processing a
path with backslashes under Unix).
