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.
