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
