Interfacing C Code to Shell Script

[Rose Oguz]

Hello to Everyone!

	I apologize if the question I ask has been asked before; I'm new 
and probably missed the posting.

	I want to call a shell script from my C program.  However, I 
would like the script to return values to my C program.  Is there a
way to do this?  Or must I write the shell output to a file and read the
contents of the file in my C code?  Any ideas, suggestions, hints, etc.
will be greatly appreciated.

					Thanks,
