A chat client made in C
You will need GTK+2.0: apt-get install gtk+-2.0
Run gcc client.c -o client `pkg-config --cflags --libs gtk+-2.0` on your Linux terminal. Then run ./client, or run make and then run ./client.
void initConnection(GtkWidget *button, gpointer data) collects username, ip and port. This data has to be sent to server. Also, data received from request has to be saved here.
void changeStatus(GtkWidget *combo, gpointer data) collects user status. This has to be sent to server.
void sendMessage(GtkWidget *button, gpointer data) collects the current message sent by user. This has to be sent to server.
void fetchUsers(gpointer data) has to make a request to server for userlist. Then you have to save user list to user array in the ChatClient struct. Also ((ChatClient *)data)->totalUsers = 2; has to be changed to be equal to user list size after making the request. And all dummy data has to be wiped out. Same thing happens with void fetchMessages(gpointer data).
