To answer my own question just in case it might help, Olivier, yes it is possible to replace the embedded in_addr structure 
member in socketaddr_in with an integer.

Structure:
Public Struct SockAddr_in
  SinFamily As Short
  SinPort As Short
  SinAddr As Integer
  _pad[8] As Byte ' Be sure to include the padding
End Struct

Code to stuff the address with `inet_pton`:
  DestAddr.SinFamily = AF_INET
  DestAddr.SinPort = 0
  rc = inet_pton(AF_INET, "8.8.8.8", VarPtr(iSinAddr)) ' Use a substitute var as VarPtr(DestAddr.SinAddr) will not work.
  If rc < 1 Then
    Print "Error converting address."
    Quit
  Endif
  DestAddr.SinAddr = iSinAddr


I hope you are able to effectively sort out this thread and implement a solution that works for you. :-)

And, thank you for the "Socket_Linux_documentation" PDF. I have saved it for future reference.
