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