ntohs function (winsock.h)
The ntohs function converts a u_short from TCP/IP network byte order to host byte order (which is little-endian on Intel processors).
Syntax
u_short ntohs(
[in] u_short netshort
);
Parameters
[in] netshort
A 16-bit number in TCP/IP network byte order.
Return value
The ntohs function returns the value in host byte order. If the netshort parameter is already in host byte order, then this function will reverse it. It is up to the application to determine if the byte order must be reversed.
Remarks
The ntohs function takes a 16-bit number in TCP/IP network byte order (the AF_INET or AF_INET6 address family) and returns a 16-bit number in host byte order.
The ntohs function can be used to convert an IP port number in network byte order to the IP port number in host byte order.
The ntohs function does not require that the Winsock DLL has previously been loaded with a successful call to the WSAStartup function.
Windows 8.1 and Windows Server 2012 R2: This function is supported for Windows Store apps on Windows 8.1, Windows Server 2012 R2, and later.
