Invoking an executable.

Well, this is basically covered in a programming topic, but, how does one execute another binary from a c code? like the system function in perl. how does one achieve the same on linux?

yes, and its execle() but the problem is that these functions dont return control to the calling prog. i need control back after the prog. ends.

Hi

I'm no coder, but you have a system function in c as well, where you can call an external binary to be executed:

system("/path/to/executable_to_run");

This works when calling a shell script at least, and I'm able to return control to the c program after calling the shell script.
