PtConnectionServerSetError()

Set the error-handler function for the server-side of a connection

Synopsis:

PtConnectionServerErrorFunc_t *
    PtConnectionServerSetError(
        PtConnectionServer_t *connection,
        PtConnectionServerErrorFunc_t *func );

Library:

ph

Description:

This function sets up an error handling function for the server-side of a connection. The prototype of the handler is:

typedef int PtConnectionServerErrorFunc_t(
                PtConnectionServer_t *connection,
                int err,
                enum PtConnectionServerError where );

The where argument indicates where the error occurred:

Pt_CONNECTION_REPLY_FAILED

The MsgReply() to the client failed.

Pt_CONNECTION_REALLOC_RECEIVE

The realloc() failed to expand the receive buffer.

Pt_CONNECTION_SERVER_BROKEN

The client has died or closed its part of the connection.

Pt_CONNECTION_MSGREAD_FAILED

The MsgRead() from the client failed.

The error handler is called when certain errors occur; the handler can return Pt_CONTINUE to retry, or Pt_END to fail. The default error handler returns Pt_END.

If your application has created its own channel without _NTO_CHF_COID_DISCONNECT and _NTO_CHF_DISCONNECT set, this mechanism won't work. For more information, see PhChannelAttach().

Returns:

A pointer to the previous error-handler function.
