system(3) behaviour under Esix rev. D

[Glenn Geers]

Hi,
	I've got a program that is setuid root that runs a system command
via the system(3) library routine. The problem is that I need the effective
uid of the calling program to be inherited by the process run by system(3).
Esix does not seem to do this. If I use my own fork/exec sequence I have no
problems. The question is: Should system(3) really set the uid of the process
it runs to the effective uid of the invoking program or to its real uid?
I have RTFM'd and the former case seems correct but the latter is occuring.


Any thoughts appreciated.
Thanks,
Glenn
