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.

Error Codes

WSANOTINITIALISED	A successful WSAStartup must occur before using this function.
WSAENETDOWN	The network subsystem has failed.
WSAENOTSOCK	The descriptor is not a socket.
WSAEFAULT	The lpnetshort argument is not totally contained in a valid part of the user address space.
