Example - TCP echo server |
- Copy
mongoose.c
andmongoose.h
to your build tree - Write code that uses the Mongoose API, e.g. in
my_app.c
- Compile application:
$ cc my_app.c mongoose.c
#include "mongoose.h" // Include Mongoose API definitions
// Define an event handler function
static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
struct mbuf *io = &nc->recv_mbuf;
switch (ev) {
case MG_EV_RECV:
// This event handler implements simple TCP echo server
mg_send(nc, io->buf, io->len); // Echo received data back
mbuf_remove(io, io->len); // Discard data from recv buffer
break;
default:
break;
}
}
int main(void) {
struct mg_mgr mgr;
mg_mgr_init(&mgr, NULL); // Initialize event manager object
// Note that many connections can be added to a single event manager
// Connections can be created at any point, e.g. in event handler function
mg_bind(&mgr, "1234", ev_handler); // Create listening connection and add it to the event manager
for (;;) { // Start infinite event loop
mg_mgr_poll(&mgr, 1000);
}
mg_mgr_free(&mgr);
return 0;
}
