getuid() seems to always return the effective user id, and getgid()
always returns the effective group id. I compiled and ran the following...
/* tmp.c */
main()
{
printf("getuid = %d, geteuid = %d\n",getuid(),geteuid());
printf("getgid = %d, getegid = %d\n",getgid(),getegid());
}
57% cc tmp.c
58% a.out
getuid = 290, geteuid = 290
getgid = 6, getegid = 6
59% whoami
local
60% su
Password:
# 51% a.out
getuid = 0, geteuid = 0
getgid = 0, getegid = 0
# 52% whoami
root
# 53%
This is wrong, isn't it. I thought that getuid() should return the
same thing after I did the su.
I discovered this in emacs (18.52) using the functions (user-uid)
and (user-real-uid) which call geteuid() and getuid() respectivly. Am
I doing something wrong here, how do I fix it.
