I haven't got the Allegro docs here so my reply is based on memory only:

attrib should be a set of flag FA_* for matching files not only with
filenames
but also with attributes. (Have a look at libc docs 'findfirst' for more
info)

param is an optional argument which gets passed to your callback function
for
every call.

>for_each_file("*.map", NULL, callback(), NULL);
Here you have to specify a pointer to "callback" function! remove the "()"
because this way you are making a call to it!
