◆ createChannel()

virtual IChannel* agora::rtc::IRtcEngine2::createChannel ( const char *  channelId)
pure virtual

Creates and gets an IChannel object.

To join more than one channel, call this method multiple times to create as many IChannel objects as needed, and call the joinChannel method of each created IChannel object.

After joining multiple channels, you can simultaneously subscribe to streams of all the channels, but publish a stream in only one channel at one time.

Parameters
channelIdThe unique channel name for an Agora RTC session. It must be in the string format and not exceed 64 bytes in length. Supported character scopes are:
  • All lowercase English letters: a to z.
  • All uppercase English letters: A to Z.
  • All numeric characters: 0 to 9.
  • The space character.
  • Punctuation characters and other symbols, including: "!", "#", "$", "%", "&", "(", ")", "+", "-", ":", ";", "<", "=", ".", ">", "?", "@", "[", "]", "^", "_", " {", "}", "|", "~", ",".
Note
  • This parameter does not have a default value. You must set it.
  • Do not set it as the empty string "". Otherwise, the SDK returns ERR_REFUSED (5).
Returns
  • The IChannel object, if the method call succeeds.
  • An empty pointer NULL, if the method call fails.
  • ERR_REFUSED(5), if you set channelId as the empty string "".
