Hi there,

I know how I could go about running a program from inside a C program
(using system or exec*) but neither seem to return the return value of
the program.  Is there an ANSI or POSIX way of obtaining the programs
return value?  If so, how?

Also, do you suppose it's portable to return pointers from executables? 
It seems to me that any system would be able to return a pointer pretty
easily, considering pointers are almost always size_of(int) and int
seems to be returned all the time.  I'm just wondering if there are any
odd problems I should know about.

Jeff
