tsnet

tsnet is simple server network library

single thread server
complete nonblocking
event driven
only support tcp(if necessary UDP support add)

And you need gcc, make, cmake, golang(for client tester) installed to compile.

example (echo server)

#include "tsnet.h"

void accept_cb(TSNET *tsnet, socket_t client_fd, uint8_t *data, ssize_t data_len)
{
  struct tsnet_client client;

  if ( tsnet_get_client_info(tsnet, client_fd, &client) < 0 ) {
    fprintf(stderr, "%s\n", tsnet_get_last_error());
    return;
  }

  printf("connected with (%d:%s:%d)\n", client_fd, client.ip, client.port);
}

void recv_cb(TSNET *tsnet, socket_t client_fd, uint8_t *data, ssize_t data_len)
{
  if ( tsnet_send(tsnet, client_fd, data, data_len) < 0 ) {
    fprintf(stderr, "%s\n", tsnet_get_last_error());
  }
}

void close_cb(TSNET *tsnet, socket_t client_fd, uint8_t *data, ssize_t data_len)
{
  struct tsnet_client client;

  printf("disconnected with (%d:%s:%d)\n", client_fd, client.ip, client.port);
}

int main(int argc, char **argv)

    fprintf(stderr, "%s\n", tsnet_get_last_error());
    goto out;
  }

  (void)tsnet_addListener(tsnet, TSNET_EVENT_CLOSE, close_cb)
