Types

TAsyncStylesA set of TAsyncStyle elements.
TClientTypeDescribes whether the client is blocking or unblocking.
TCMLookupCompleteIs used internally.
TCMSocketMessageIs used internally.
TErrorEventRepresents the error type.
TGetSocketEventThe type for event handlers that respond to events during the expected course of forming or using a socket connection.
TGetThreadEventThe type for event handlers that respond to events during the execution of threads that handle individual client connections.
TLookupStateIndicates any asynchronous activities occurring while opening a connection.
TServerTypeDescribes whether the server is blocking or thread blocking.
TSocketErrorEventTSocketErrorEvent is the type for event handlers that respond when a Windows socket reports an error.
TSocketErrorProcThe type that represents the exception handler for error messages that are received from a Windows socket connection.
TSocketEventTSocketEvent identifies the operation that a socket is performing.
TSocketEventEventThe type for event handlers that notify that an event has occurred to a socket connection and also to the operation it is currently performing.
TSocketNotifyEventThe type for event handlers that notify that an event has occurred to a certain socket connection.
