Within the DJGPP framework, stat() and fstat() are the proper answer.

For an "extremely portable" program, you cannot do this at all, since
the ANSI C standard doesn't even assume there is any such thing as a
"directory". To it, a filename is an opaque entity without further
structure inside. Only in the realm of other, less widely applicable
standards, like POSIX, you have functions like opendir()/readdir() to
work with directories.

That's simple: use strcmp() or strstr() to search for them in the
filenames, once you have them.
