This 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] Descriptor identifying a socket. - netshort
[in] 16-bit number in network byte order. - lphostshort
[out] Pointer to a 16-bit number in host byte order.

| WSAEFAULT | The lphostshort parameter is not completely contained in a valid part of the user address space. |
Remarks
This function 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.
