Hello Guys,
I have this server program (see below) ans i have to make a graphic Client with phAB to communicate with the server.
when there is a connection between both, it has a display a container, if not , then simply an error message.
this is the server programm :
/*
- ResMgr and Message Server Process
*/
#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>

#include <sys/dispatch.h>

char msg_data[255];

int num;
char msg_reply[255];
/* cast a pointer to the message data */
