(This works on BSD4.3). Is there some workaround, or is this another reason to wait for System V.4? #includemain () { int egid, gid; egid = getegid(); gid = getgid(); printf("egid = %d gid = %d\n", egid, gid); if (egid != 1) { fprintf(stderr, "must install this file setgid '1'"); exit(0); } if (setgid(1) < 0) { fprintf(stderr, "failed to setgid(1)"); exit(0); } egid = getegid(); gid = getgid(); printf("egid = %d gid = %d\n", egid, gid); if (gid != 1) { fprintf(stderr, "setgid(1) does not work!"); exit(0); } printf("setgid(1) does work!"); } -- Tan Bronson (home) tan@microvation.com (or tan@bronson.uucp) Microvation Consultants (work) bronson@multiflow.com Madison, CT 06443
