{
Modified by Mike Caughran Cedar Island Software Nov 1994
Changed references to SOCKET to tSOCKET
added INADDR_ANY
added PInteger
}
{Nochmal modifiziert: INC+PAS-Dateien zusammengeführt,
Strukturen Pascal-like umgebaut (mit "T" und "P") sowie
unsinnige Komponentenpräfixe entfernt (z.B. sin_addr --> addr).
Die Strukturen SOCKADDR und SOCKADDR_IN wurden zu einer
verschachtelten Struktur TSockAddr zusammengeführt.
Eine handhabbare, statisch linkbare Funktion "OpenSock"
wurde hinzugefügt.
Another modification: one File (no .INC file),
structures modified with "T" and "P" prefixes,
removed old-c-style record component prefixes (e.g. sin_addr --> addr),
removed structure SOCKADDR_IN and enhancement of SOCKADDR
to a record/union TSockAddr with all required components.
Added static library function "OpenSock()".
