## Detailed Description

This section explains the concept of channels where users can interact.

Users are arranged in a tree structure consisting of channels where each channel can hold a number of users. While in a channel users can transmit audio and video to each other as well as sending channel messages. On a server there will always be a root channel which cannot be deleted.

In other conferencing tools channels are also refered to as "rooms".

Sections:

- Channel Administration
- File Sharing
- Storing Conversations to Audio Files

# Channel Administration

To create a new channel on a server requires UserRight.USERRIGHT_MODIFY_CHANNELS or UserRight.USERRIGHT_CREATE_TEMPORARY_CHANNEL.

With UserRight.USERRIGHT_MODIFY_CHANNELS the method TeamTalkBase.DoMakeChannel() can be used to create a new channel and any existing channel can be updated using TeamTalkBase.DoUpdateChannel() and removed by calling TeamTalkBase.DoRemoveChannel(). Basically UserRight.USERRIGHT_MODIFY_CHANNELS gives unrestricted access to all channels on the server. Also seeing passwords of all channels on the server.

With UserRight.USERRIGHT_CREATE_TEMPORARY_CHANNEL the user can only create temporary channels which disappear when the last user leaves the channel. A temporary channel must be created by calling TeamTalkBase.DoJoinChannel(). Once a user has created a temporary channel and joined it he becomes operator of the channel which means that he can update the channel's properties at any given time.

# File Sharing

While in a channel users can upload and download files if the UserRight.USERRIGHT_UPLOAD_FILES and UserRight.USERRIGHT_DOWNLOAD_FILES are enabled. To upload a file to a channel the channel needs to have a disk quota. The disk quota is specified by nDiskQuota in the BearWare.Channel-struct. The file being uploaded must have a file size which is less than the disk quota and the sum of sizes of existing files. Once a file is uploaded only channel operators and the file's owner can delete a file.

Call TeamTalkBase.DoSendFile() to upload a file and TeamTalkBase.DoRecvFile() to download a file. Only users who have a BearWare.UserAccount on the server are allowed to upload files. There is no limit on the maximum number of file transfers but it is advised to queue file transfers so the file transfers do no affect server performance.

# Storing Conversations to Audio Files

In some applications it may be required to be able to save all audio data received by the client instance to disk. This can be archived by calling TeamTalkBase.SetUserMediaStorageDir() which will then save received audio data in the following format: "YYYYMMDD-HHMMSS \#USERID USERNAME.wav". USERNAME is the szUsername from BearWare.User.

To store audio data from outside the local client instance's channel, please read section Spying on Users.

## Enumeration Type Documentation

## ◆ ChannelType

enum BearWare.ChannelType : uint

The types of channels supported.

  Channel

Enumerator
CHANNEL_DEFAULT | A default channel is a channel which disappears after the last user leaves the channel.
CHANNEL_PERMANENT | A channel which persists even when the last user leaves the channel.
CHANNEL_SOLO_TRANSMIT | Only one user can transmit at a time.
CHANNEL_CLASSROOM | Voice and video transmission in the channel is controlled by a channel operator. For a user to transmit audio or video to this type of channel the channel operator must add the user's ID to `transmitUsers` in the BearWare.Channel struct and call TeamTalkBase.DoUpdateChannel().
