ntohll function

The ntohll inline function converts an unsigned __int64 from TCP/IP network order to host byte order (which is little-endian on Intel processors).

Syntax


u_long __inline ntohll(
  unsigned __int64 value
);

Parameters

value

An unsigned __int64 number in TCP/IP network byte order.

Return value

The ntohll function returns the value supplied in the value parameter with the byte order reversed. If value 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 ntohll inline function takes an unsigned __int64 number in TCP/IP network byte order (the AF_INET or AF_INET6 address family) and returns a 32-bit number in host byte order.

The ntohll function can be used to convert an IPv4 address in network byte order to the IPv4 address in host byte order. This function does not do any checking to determine if the value parameter is a valid IPv4 address.

The ntohll function does not require that the Winsock DLL has previously been loaded with a successful call to the WSAStartup function.
