Overview
- unit WSocket.pas
- inheritance
TWSocket component is implementing the TCP protocol described in RFC 793 and and UDP protocol described in RFC 768. Both protocols are encaptulated by the IP protocol described in RFC 791. TWSocket is used in almost every other ICS component.
TWSocket component can be used as client or a server. For its use as TCP server however TWSocketServer is encouraged because of his advanced features.
