fork/execvp

Code:

---

if(count > 1){ //fork()
                        printf("START OF WHILE - %i \n", count);
                                int cid = fork();
                                count--;
                                printf("1st: %i \n", count);
                                if(cid == 0){ //Child process
                                        printf("%i \n", cid);
                                        execvp(cmdTokens[0], cmdTokens);
                                } else if(cid > 0){ //Parent process
                                        waitpid(cid, 0, 0);
                                        printf("%i \n", cid);
                                        execvp(cmdTokens[0], cmdTokens);
                                }
                                printf("END OF LOOP \n");
                        printf("END OF WHILE - %i \n", count);
                }

For some reason, my code only gets to the else if statement and does not go to the "printf("END OF LOOP \n");" Does anyone know why this might be?

From the man page of execve:

Code:

---

DESCRIPTION
      The exec family of functions shall replace the current process image with a new process image. The new image shall be constructed from a regular, executable file called the  new  process
      image file. There shall be no return from a successful exec, because the calling process image is overlaid by the new process image.

---

The exec family of functions never returns.

Hmm... that helped a bit. Let me test a few things out and see what happens.
