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