2. Socket (int Af, int Type, int proctocol)
3. INT Bind (socket S, Strut SockAddr_in * name, int namelen);
Struct sockaddr_in {
Short sin_family;
UNSIGNED SIN_PORT;
Struct in_addr sin_addr;
Char sin_zero [8];
}
Struct in_addr {
Union {
Struct {
Unsigned char s_b1, s_b2, s_b3, s_b4,
} s_un_b;
Struct {
UNSIGNED SHORT S_W1, S_W2;
} S_UN_W;
Unsigned long s_addr;
} S_um;
}
INT Listen (socket S, Struct SockAddr_in * addr, int * addrlen);
INT Connect (socket S, Struct SockAddr_in * name, int namelen);
Int Send (Socket S, Char * BUF, INT LEN, INT FLAGS);
Int Recv (Socket S, CHAR * BUF, INT LEN, INT FLAGS);
Sockets with data packets communications do not have to be established, you can skip the connection directly
Int Recvfrom (Socket S, Char * Buf, Int Len, Int Flags, Struct SockAddr_infrom, in * fromlen);
Int Sendto (Socket S, Char * BUF, INT LEN, INT FLAGS, STRUCT SOCKADDR_INTO, INT * TOLEN);
CloseSocket (Socket S);
I still want to draw a picture, I don't know how to paint.
