Hello,

is it possible to get the subnetmask of the local PC network adapters? We
get the IP adresses of the local PC with the function gethostbyname()
additionaly we need the subnetmask but how to get it?

Regards

Andreas

Yes.  Use the GetAdaptersInfo() function from the IP Helper API:

    GetAdaptersInfo
    http://msdn2.microsoft.com/en-us/library/aa365917.aspx

> We get the IP adresses of the local PC with the function

That is a socket API function.  The socket API does not provide subnet
information.
