    void Loadexternal ( char *emu, char *rom )

{

	pid_t pid;

    printf("%s %s \n", emu, rom);

	if ((pid = fork()) == 0) {

		char * const new_argv[] = { emu, rom, NULL };

        

		if (execv(new_argv[0], new_argv) < 0) {

			perror("execv error");

            exit(EXIT_FAILURE);

		}

	} else if (pid < 0) {

		perror("fork error");

		exit(EXIT_FAILURE);

	}

    

	/* You really should use waitpid here so you know when the 

	 * "emu" exits and you can startup the "frontend" again. */

	if (waitpid(pid, NULL, 0) == -1) {

		perror("waitpid error");

		exit(EXIT_FAILURE);

	}

    

	printf("Exited successfully\n");

}

But the trick is, it needs to be somewhere out of the way of the vm's because it gives me compiling errors because it includes system files

    #include <stdio.h>

#include <stdlib.h>

#include <unistd.h>

#include <sys/types.h>

#include <sys/wait.h>

so it needs to be in the client code. The reason being is i need to call it from the ui. I did this by putting it in cl_ui.c but it has to go from the ui vm, through the syscalls, then to the client, and its hard to get arguments to pass correctly doing this, is there a better way of doing this? If more info is needed let me know, thank you in advance.
