The best example I have is the mkdir command.  Since a normal
user can not create a directory. The mkdir (under Unix) is a SUID root
program. That is, when the program is envoked its effective user id is
that of the super user (stupid user :-)) root.

To make a directory from you C program (unless your program is
SUID root) you must use the system call (with the appropriate checks
for success).

	system( "mkdir mydir" );
