Obtain all IP addresses of the local machine.

Recently, due to the need for a management software for penetrating Internet cafes to restrict vswitches and vrouters. I set 10 IP addresses for the local machine to receive data from hardware.
I need to get all the IP addresses of the local machine.
Now, you have prepared and used it later.

Bool getlocalall_ipaddress (cstringarray & strarrayip)
{
Char szhostname [100];
Struct addrinfo * res;
Struct addrinfo * Next = NULL; Word version;
Wsadata data; version = makeword (0x02, 0x02);: wsastartup (version, & data );

If (socket_error =: gethostname (szhostname, sizeof (szhostname )))
{
: Wsacleanup (); Return false;
} // The getaddrinfo API does not find the entry point in ws2_32.dll of Window 2000 and does not export this function.If (0! = Getaddrinfo (szhostname, null, null, & res ))
{
: Wsacleanup (); Return false;
} /**//*
