A list of code examples used in class and any board work or other artifacts I create during class. This page generally will be added to shortly before or shortly after the class (or sometime both).

mp5startercode.c creates a socket listener and detached threads.
In class I added this code to client_thread:
while(1) {
char buffer[4096+1];
ssize_t got = read(fd, buffer, 4096);
buffer[got] = '\0';
printf("Buffer: %s (%ld)\n", buffer, got);
write(fd, "Thank you for your message!\n", strlen("Thank you for your message!\n"));
}In class I also had trouble running telnet in the docker image. Here’s the steps to use it:
either (once) add telnet to the line that currently says make in your Dockerfile and then select Rebuild container
in the remote menu in VS Code
or (each time you start docker) run apt update; apt install telnet from the command line.
From the docker command line, run telnet localhost 1234, replacing 1234 with the port you want to use.
