GDay everyone,
I have a problem that I spent so much time on it.
How can I fix my code(below) to output the buffer msg_cat in function A from function B ?
Please help if you're interested in.
I'd appreciate it.

Code:
void A(){
char *msg;
char msg_cat[100] = "";
//Receive multicasted messages from server and store in msg buffer.
msg = (char *)recvfromDST (&read_EP, sockMulti);
//Concatenate message msg into buffer msg_cat.
strcat(msg_cat, msg);
strcat(msg_cat, "\n");
}
void B(){
if (strncmp(KB_buff, "display", 7) == 0){
//output to screen here
}
}
