access bash from C program?

[Labitt, Bruce]

That is what I do now.  I was wondering if there was a programmatic or
more elegant way...

The way that has been suggested would be roughly

	a=getrlimit;  //save current setting
	ulimit	  // do what I want
	setrlimit=a	  // restore setting

?
Thanks,
-Bruce

Come to think of it, it'd probably just be easier to run ulimit before 
you run the C program.
