A socket library for C that makes writing socket programs a cinch. The library models the simplicity of Python's socket library API. If you can create a socket in Python, you can just as easily create one using this class! Currently the library will only work on Linux.
- Support Windows
- Implement raw sockets
This library depends on class.c from my c-functions library.
Instantiate the socket object:
Socket *s = init_socket(AF_INET, SOCK_STREAM);
Where AF_INET is the address family, and SOCK_STREAM is the socket type.
Then either connect to act as a client, or bind, listen, and accept to act as a server.
Use send and recv to send and receive data to/from the client/server.
When you're done, destroy the object:
socket_close(s);
These examples are also in the tests/ directory.
The server:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "socket.h"
int main()
{
char buff[100];
int bytes;
Socket *s = init_socket(AF_INET, SOCK_STREAM);
s->bind(s, NULL, 12345);
s->listen(s, 5);
ClientAddr client_addr;
Socket *c = s->accept(s, &client_addr);
printf("Client connected at %s:%d\n", client_addr.ip_addr, client_addr.port);
while (1) {
c->recv(c, buff, sizeof(buff));
printf("Got: %s\n", buff);
c->send(c, buff);
printf("Sending: %s\n", buff);
}
socket_close(c);
socket_close(s);
}
The client:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "socket.h"
int main()
{
int bytes;
char buff[100];
Socket *s = init_socket(AF_INET, SOCK_STREAM);
s->connect(s, "127.0.0.1", 12345);
while (1) {
memset(buff, 0, sizeof(buff));
printf(">> ");
if (fgets(buff, sizeof(buff), stdin) == NULL) {
perror("fgets error");
break;
}
s->send(s, buff);
s->recv(s, buff, sizeof(buff));
printf("Received: %s\n", buff);
}
socket_close(s);
}
