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 CLIENTEVENT_CMD_ERROR. An example of a server command error could be to issue the TT_DoLogin command with an incorrect password. The server will in this case respond with the error 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 INTERR_SNDINPUT_FAILURE and INTERR_SNDOUTPUT_FAILURE.
| typedef enum ClientError ClientError |
Errors which can occur either as a result of client commands or as a result of internal errors.
Use TT_GetErrorMessage to get a text-description of the error.
| typedef struct ClientErrorMsg ClientErrorMsg |
Struct containing an error message.
| enum ClientError |
Errors which can occur either as a result of client commands or as a result of internal errors.
Use TT_GetErrorMessage to get a text-description of the error.
| Enumerator | |
|---|---|
| CMDERR_SUCCESS | Command indicating success. Only used internally. |
| CMDERR_SYNTAX_ERROR | Command has syntax error. Only used internally. |
| CMDERR_UNKNOWN_COMMAND | The server doesn't support the issued command. This error may occur if the server is an older version than the client instance. |
| CMDERR_MISSING_PARAMETER | Command cannot be performed due to missing parameter. Only used internally. |
| CMDERR_INCOMPATIBLE_PROTOCOLS | The server uses a protocol which is incompatible with the client instance. |
| CMDERR_UNKNOWN_AUDIOCODEC | The server does not support the audio codec specified by the client. Introduced in version 4.1.0.1264.
|
| CMDERR_INVALID_USERNAME | Invalid username for UserAccount.
|
| CMDERR_INCORRECT_CHANNEL_PASSWORD | Invalid channel password. The #TT_DoJoinChannel or #TT_DoJoinChannelByID passed an invalid channel password. #TT_DoMakeChannel can also cause a this error if the password is longer than #TT_STRLEN. |
| CMDERR_INVALID_ACCOUNT | Invalid username or password for account. The #TT_DoLogin command was issued with invalid account properties. This error can also occur by #TT_DoNewUserAccount if username is empty. |
| CMDERR_MAX_SERVER_USERS_EXCEEDED | Login failed due to maximum number of users on server. TT_DoLogin failed because the server does not allow any more users. |
| CMDERR_MAX_CHANNEL_USERS_EXCEEDED | Cannot join channel because it has maximum number of users. TT_DoJoinChannel or TT_DoJoinChannelByID failed because no more users are allowed in the channel. |
| CMDERR_SERVER_BANNED | IP-address has been banned from server. #TT_DoLogin failed because the local client's IP-address has been banned on the server. |
| CMDERR_NOT_AUTHORIZED | Command not authorized. The command cannot be performed because the client instance has insufficient rights. @see TT_DoDeleteFile @see TT_DoJoinChannel @see TT_DoJoinChannelByID @see TT_DoLeaveChannel @see TT_DoChannelOp @see TT_DoChannelOpEx @see TT_DoKickUser @see TT_DoUpdateChannel @see TT_DoChangeNickname @see TT_DoChangeStatus @see TT_DoTextMessage @see TT_DoSubscribe @see TT_DoUnsubscribe @see TT_DoMakeChannel @see TT_DoRemoveChannel @see TT_DoMoveUser @see TT_DoUpdateServer @see TT_DoSaveConfig @see TT_DoSendFile @see TT_DoRecvFile @see TT_DoBanUser @see TT_DoUnBanUser @see TT_DoListBans @see TT_DoListUserAccounts @see TT_DoNewUserAccount @see TT_DoDeleteUserAccount |
| CMDERR_MAX_DISKUSAGE_EXCEEDED | Cannot upload file because disk quota will be exceeded. #TT_DoSendFile was not allowed because there's not enough disk space available for upload. @see Channel |
| CMDERR_INCORRECT_OP_PASSWORD | Invalid password for becoming channel operator. The password specified in #TT_DoChannelOpEx is not correct. The operator password is the @a szOpPassword of the #Channel-struct. |
| CMDERR_AUDIOCODEC_BITRATE_LIMIT_EXCEEDED | The selected AudioCodec exceeds what the server allows. A server can limit the vitrate of audio codecs if @c nAudioCodecBpsLimit of #ServerProperties is specified. |
| CMDERR_MAX_LOGINS_PER_IPADDRESS_EXCEEDED | The maximum number of logins allowed per IP-address has been exceeded.
|
| CMDERR_MAX_CHANNELS_EXCEEDED | The maximum number of channels has been exceeded.
|
| CMDERR_COMMAND_FLOOD | Command flooding prevented by server. Commands are issued faster than allowed by the server. See #UserAccount @c commandsPerMSec. @see TT_CHANNELID_MAX |
| CMDERR_CHANNEL_BANNED | Banned from joining a channel. @see TT_DoJoinChannel() @see TT_DoJoinChannelByID() @see TT_DoBanUser() |
| CMDERR_NOT_LOGGEDIN | Client instance has not been authenticated. #TT_DoLogin has not been issued successfully or #TT_DoLogout could not be performed because client instance is already logged in. |
| CMDERR_ALREADY_LOGGEDIN | Already logged in. #TT_DoLogin cannot be performed twice. |
| CMDERR_NOT_IN_CHANNEL | Cannot leave channel because not in channel. #TT_DoLeaveChannel failed because user is not in a channel. |
| CMDERR_ALREADY_IN_CHANNEL | Cannot join same channel twice. #TT_DoJoinChannel or #TT_DoJoinChannelByID failed because client instance is already in the specified channel. |
| CMDERR_CHANNEL_ALREADY_EXISTS | Channel already exists. #TT_DoMakeChannel failed because channel already exists. |
| CMDERR_CHANNEL_NOT_FOUND | Channel does not exist. Command failed because channel does not exists. @see TT_DoRemoveChannel @see TT_DoUpdateChannel @see TT_DoMakeChannel Due to invalid channel name @see TT_DoSendFile @see TT_DoRecvFile @see TT_DoDeleteFile @see TT_DoJoinChannel @see TT_DoJoinChannelByID @see TT_DoLeaveChannel @see TT_DoChannelOp @see TT_DoKickUser @see TT_DoBanUser @see TT_DoMoveUser @see TT_DoTextMessage |
| CMDERR_USER_NOT_FOUND | User not found. Command failed because user does not exists. @see TT_DoChannelOp @see TT_DoKickUser @see TT_DoBanUser @see TT_DoMoveUser @see TT_DoTextMessage @see TT_DoSubscribe @see TT_DoUnsubscribe |
| CMDERR_BAN_NOT_FOUND | Banned IP-address does not exist. #TT_DoUnBanUser failed because there is no banned IP-address which matches what was specified. |
| CMDERR_FILETRANSFER_NOT_FOUND | File transfer doesn't exists. TT_DoSendFile() or TT_DoRecvFile() failed because the server cannot process the file transfer. |
| CMDERR_OPENFILE_FAILED | Server failed to open file. TT_DoSendFile() or TT_DoRecvFile() failed because the server cannot open the specified file (possible file lock). |
| CMDERR_ACCOUNT_NOT_FOUND | Cannot find user account. #TT_DoDeleteUserAccount failed because the specified user account does not exists. |
| CMDERR_FILE_NOT_FOUND | File does not exist. #TT_DoSendFile, #TT_DoRecvFile or #TT_DoDeleteFile failed because the server cannot find the specified file. |
| CMDERR_FILE_ALREADY_EXISTS | File already exist. #TT_DoSendFile failed because the file already exists in the channel. |
| CMDERR_FILESHARING_DISABLED | Server does not allow file transfers. #TT_DoSendFile or #TT_DoRecvFile failed because the server does not allow file transfers. |
| CMDERR_CHANNEL_HAS_USERS | Cannot process command since channel is not empty. @see TT_DoUpdateChannel #AudioCodec cannot be changed while there are users in a channel. |
| CMDERR_LOGINSERVICE_UNAVAILABLE | The login service is currently unavailable. Added in TeamTalk v5.3 to support web-logins. |
| CMDERR_CHANNEL_CANNOT_BE_HIDDEN | Cannot apply CHANNEL_HIDDEN to Channel's type. A hidden channel cannot contain subchannels or have it #CHANNEL_HIDDEN property toggled. |
| INTERR_SNDINPUT_FAILURE | A sound input device failed. This can e.g. happen when joining a channel and the sound input device has been unplugged. Call #TT_CloseSoundInputDevice and TT_InitSoundInputDevice with a valid #SoundDevice to releave the problem. |
| INTERR_SNDOUTPUT_FAILURE | A sound output device failed. This can e.g. happen when joining a channel and the sound output device has been unplugged. Note that it can be posted multiple times if there's several users in the channel. Call #TT_CloseSoundOutputDevice and TT_InitSoundOutputDevice with a valid #SoundDevice to releave the problem. |
| INTERR_AUDIOCODEC_INIT_FAILED | Audio codec used by channel failed to initialize. Ensure the settings specified in AudioCodec are valid.
|
| INTERR_SPEEXDSP_INIT_FAILED | Same as INTERR_AUDIOPREPROCESSOR_INIT_FAILED. |

| INTERR_TTMESSAGE_QUEUE_OVERFLOW | TTMessage event queue overflowed. The message queue for events has overflowed because TT_GetMessage() has not drained the queue in time. The #TTMessage message queue will suspend event handling once the queue overflows and resumes event handling again when the message queue has been drained. |
| INTERR_SNDEFFECT_FAILURE | SoundDeviceEffects failed to initialize. This error occurs when joining a channel and an effect in #SoundDeviceEffects failed to initialize. The effects are applied using TT_SetSoundDeviceEffects() |
