Detailed Description

This section explains how to handle errors occuring in the client instance or as a result of server commands.

There are two types errors which can occur in the client, either server command error or internal errors. Section Client/Server Commands describes all the commands a client can issue to a server. If a server commands fails the client instance notifies the user application through the event TeamTalkBase.OnCmdError(). An example of a server command error could be to issue the TeamTalkBase.DoLogin() command with an incorrect password. The server will in this case respond with the error ClientError.CMDERR_INVALID_ACCOUNT. The user application must be designed to process these errors so application users can be notified of errors.

Internal errors are errors due to failing devices. Currently only two such errors exist ClientError.INTERR_SNDINPUT_FAILURE and ClientError.INTERR_SNDOUTPUT_FAILURE.
