I'm not familiar with this particular routine, but one obvious problem
is that if the third parameter to `for_each_file' is supposed to be a
function pointer (e.g., a callback, as it is named), then you are
calling it wrong.  This syntax calls the function before calling
`for_each_file', rather than passing the function pointer to
`for_each_file'.  What you meant was this:

    for_each_file("*.map", NULL, callback, NULL);
