Capture the return status from a shell script using system call

P: 2

I am calling a unix script from my c program, but i need to capture the return value of the script. The system() function would return whether the script was successfully executed or not. But the return value of the script is needed within the C program.

Please help me out here.

Thanks and Regards,

You might try creating a file in your C program and then use that file as the return from your program to the script.

I have thought about that, but I can consider it as the last resort. Is there any other way of finding out the return status of the script from a c program? Any other function?

Not that I know of. Your C program must leave a mark somewhere the script can find it. The return from main() is used (or maybe not used( by the OS and therefore may not be passed on to your script.
