lite-socket

A C library that supports ipv4 tcp/udp sockets on windows and unix.

Provides basic functions for common operations and helpers for returning system error messages.

Usage

Direct

Copy the src\ folder into your project.

Compile to Shared or Static library

From the project root directory:

mkdir build
cd build
cmake ..

Example

#include "lite_socket.h"
#include <stdint.h>

int main(void) {
	socket_error_t  err;
	socket_init();
	sockfd_t sock = socket_create(TCP);

	if (sock == INVALID_SOCKET) {
		socket_error_print("socket_create", socket_error());
		exit(EXIT_FAILURE);
	}

	err = socket_tcp_nodelay(sock, 1);
	if (err) {
		socket_error_print("socket_tcp_nodelay", err);
		exit(EXIT_FAILURE);
	}

	int optval = 0;
	socklen_t optlen = sizeof(optval);
	err = socket_getsockopt(sock, IPPROTO_TCP, TCP_NODELAY, &optval, &optlen);
	if (err) {
		socket_error_print("socket_getsockopt", err);
		exit(EXIT_FAILURE);
	}


	err = socket_bind(sock, &(ipv4_t) { "127.0.0.1", 7111 });
	if (err) {
		socket_error_print("socket_bind", err);
		exit(EXIT_FAILURE);
	}

	ipv4_t name;

	err = socket_getname(sock, &name);
	if (err != SOCKET_OK) {
		socket_error_print("socket_getname", err);
	}
	else {
		printf("%s:%d, tcp_delay=%d\n", name.addr, name.port, optval);
	}

	err = socket_close(sock);
	if (err) {
		socket_error_print("socket_bind", err);
	}

	socket_cleanup();

	return 0;
