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.
