Thread: Fork + Exec + ? Question!

I am trying to accomplish a simple task... But I couldn't make it to work properly.

The code below is an attempt to "fork + execute a new process" but it is not working as I expected because when the child executes the process, it behaves differently when it is called by the parent.

Can you say what am I doing wrong?

Code:

#include <unistd.h>


long int main(long argc, char** argv, char** envp)
{
  char* fpath = "/home/ignorant/Desktop/test2";
  char* agv[] = {fpath, 0};


  int frk = fork();


  if (frk != 0)
  {
    // parent!
    if (frk > 0)
    {
      // successful! Executed program behaves OK from here...
      //execve(fpath, agv, NULL);
      return 0;
    }
    else
    {
      // failed!
      return 3;
    }
  }
  else
  {
    // child! Executed program behaves differently from here...
    execve(fpath, agv, NULL);
    return 3;
  }
}

Thank you!

I think I understood now. The parent process was being terminated.


I think it is solved.


Thanks for reading!
