htonf function (winsock2.h)
The htonf inline function converts a float from host to TCP/IP network byte order (which is big-endian).
Syntax
unsigned __int32 htonf(
float Value
);
Parameters
Value
A float that contains a number in host byte order.
Return value
The htonf function returns the value in TCP/IP's network byte order.
Remarks
The htonf inline function takes a float that contains number in host byte order and returns a 32-bit unsigned number in the network byte order used in TCP/IP networks (the AF_INET or AF_INET6 address family).
The htonf inline function can be used to convert an IPv4 address in host byte order to the IPv4 address in network byte order. This function does not do any checking to determine if the value parameter is a valid IPv4 address.
The htonf inline function does not require that the Winsock DLL has previously been loaded with a successful call to the WSAStartup function.
