It returns -1. xf86OpenConsole does some funny trick to get this to work:
/*
* change to parent process group that pgid != pid so
* that setsid() doesn't fail and we become process
* group leader
*/
if (setpgid(0,ppgid) < 0)
xf86Msg(X_WARNING, "xf86OpenConsole: setpgid failed: %s\n",
strerror(errno));
/* become process group leader */
if (setsid() < 0)
xf86Msg(X_WARNING, "xf86OpenConsole: setsid failed: %s\n",
strerror(errno));
