Scenario 9: Adding Participants

Description

You can call the API for adding participants during a meeting.

Service Process

When using the SDK to add participants, call the AddAttendee API, and implement the OnAddAttendeeResult function.

  1. Call the API.

    1. Assemble the HwmConfAttendee data structure.
    2. Call the AddAttendee API to add participants. The data in preceding steps is used as input parameters.

  2. Implement the callback function.

    Implement the OnAddAttendeeResult function.
