Re: [Freedos-user] NTFS4DOS and FreeCOM - Wildcard Problems?

[<kd...@co...>]

OK, I've done a bit more research on this problem.  The relevant
portion of the delete function appears to be, removing some
extraneous code:

if (FINDFIRST(fullname, &f, FA_ARCH)) {
				error_sfile_not_found(fullname);
			} else do {
				strcpy(p, f.ff_name);       /* Make the full path */
[...]

				if(verbose && !optP)
					displayString(TEXT_DELETE_FILE, fullname);
				if(unlink(fullname) != 0) {
					perror(fullname);   /* notify the user */
				} else
					++count;
			} while (FINDNEXT(&f) == 0);

FINDFIRST and FINDNEXT are suppl calls to findfirst and findnext which
invoke DOS calls (respectively):

	r.r_ax = 0x4e00;
	rv = invokeDOS(&r);

	r.r_ax = 0x4f00;
	rv = invokeDOS(&r);

Is it legal to do an invokeDOS on this interrupt on a non-existent file?
The unlink is done before the findnext.  There's a test case I may 
be able to duplicate...

I have run this in verbose mode and it only shows the files it is
deleting.  After the problem initially occurs, it quite consistently
deletes the first, third, fifth, etc. files on every subsequent del *.*.

This is very repeatable with NTFS4DOS and lots of files to start with.
