Thread: little help in simple socket library

I made simple socket library for use in future, it can be compile but when I create a simple server based on it, it fail to work.

Code:

#ifndef _OPENSOCKET_H_
#define _OPENSOCKET_H_

/* handle for socket */
typedef int hSOCK;

/* socket creation */
typedef struct __sock_s
 {
	 int domain;
	 int type;
	 int protocol;
 } *sock_s;

/* struct to hold socket information */
typedef struct sockaddr_in *sock_i;


hSOCK socket_open(sock_s ssock);
void socket_init(sock_i tsock);
int socket_listen(hSOCK sock, sock_i tsock, int family, const char *address, unsigned int port);
hSOCK socket_accept(hSOCK sock, sock_i csock);
int socket_connect(hSOCK sock, sock_i tsock);
int socket_send_len(hSOCK csock, char *len, int flags);
int socket_send(hSOCK sock, char *data, unsigned int len, int flags);
int socket_recv_len(hSOCK sock, int flags);
char *socket_recv(hSOCK sock, int len, int flags);
int socket_close(hSOCK sock);

#endif
