WSAHtons
The Windows
Sockets WSAHtons function converts a u_short from host byte order
to network byte order.
int WSAHtons (
|
SOCKET s, |
|
|
u_short hostshort, |
|
|
u_short
FAR * lpnetshort |
|
|
); |
|
Parameters
s
[in] A
descriptor identifying a socket.
hostshort
[in] A 16-bit
number in host byte order.
lpnetshort
[out] A
pointer to a 16-bit number in network byte order.
Remarks
This routine
takes a 16-bit number in host byte order and returns a 16-bit number pointed to
by the lpnetshort parameter in the network byte order associated with
socket s.
Return Values
If no error
occurs, WSAHtons returns zero. Otherwise, a value of SOCKET_ERROR is
returned, and a specific error code may be retrieved by calling WSAGetLastError.
