rmdir doesn't always return EINVAL.
Test program:
#include <stdlib.h>
#include <unistd.h>
#include <stdio.h>
int
main (int argc, char **argv)
{
printf ("%d = rmdir (\"%s\")\n", rmdir (*++argv), *argv);
perror ("rmdir");
}
Run it:
bash-3.00$ ./rmdir qwer
-1 = rmdir ("qwer")
rmdir: No such file or directory
bash-3.00$ ./rmdir qwer/.
-1 = rmdir ("qwer/.")
rmdir: Invalid argument
