Description

Sets the error handler for this socket.
If the socket has an error, this script is called and you can react and close the socket.


With plugin version 6.0 or newer the script name can be a script ID number. In that case the plugin queries the script name for the given script ID. This allows to call scripts by ID and avoid problems if scripts are later renamed.

Notice: FileMaker 19.2 adds a fmplugin extended privileges. If you have such an extended privileges to allow the plugin to trigger scripts, you need to grant permissions for it. If such a privilege is not defined, the plugin is allowed to trigger scripts. See FileMaker product documentation for details.

Examples

Set Variable [$$sock; Value:MBS("Socket.NewTCPSocket")]
If [MBS("IsError")]
    Show Custom Dialog ["Failed to create Socket"; $$sock]
    Exit Script []
End If
Set Variable [$r; Value:MBS("Socket.SetNewConnectionHandler"; $$sock; Get(FileName); "NewConnection")]
Set Variable [$r; Value:MBS("Socket.SetErrorHandler"; $$sock; Get(FileName); "SocketError")]
Set Variable [$r; Value:MBS("Socket.Listen"; $$sock; TCP Receiver::ListenPort)]
If [MBS("IsError")]
