WSAHtonl
The Windows
Sockets WSAHtonl function converts a u_long from host byte order
to network byte order.
int WSAHtonl (
|
SOCKET s, |
|
|
u_long hostlong, |
|
|
u_long FAR
* lpnetlong |
|
|
); |
|
Parameters
s
[in] A
descriptor identifying a socket.
hostlong
[in] A 32-bit
number in host byte order.
lpnetlong
[out] A
pointer to a 32-bit number in network byte order.
Remarks
This routine
takes a 32-bit number in host byte order and returns a 32-bit number pointed to
by the lpnetlong parameter in the network byte order associated with
socket s.
Return Values
If no error
occurs, WSAHtonl returns zero. Otherwise, a value of SOCKET_ERROR is
returned, and a specific error code may be retrieved by calling WSAGetLastError.
