C language "execv" question
--------------------------------------------------------------------------------

main()
{
execv("Filter.EXE",NULL)
printf("\n executed the file\n");
getch();
}

What I am trying to do is execte the file Filter.exe and try to get the controll back to my program. Filer executes properly, but the printf statement doesnot work. I dont have the source code for filter.exe. Can some one help how to get back the control to my program.

Hi, please do ask your questions in the C/C++ Forum section, not in the C/C++
Articles section. I'll move your question to that forum for you.

kind regards,

The exec family of functions are newbie traps. That's because the temptation is to guess that execv "executes" either code or an executable separately. Reading the documentation hits something more indepth:

The exec family of functions replaces the current process image with a new process image.

If you just want to run another program, use the system function, declared within stdlib.h .
