C++ (Cpp) Child::GetIndirectMessageCount Examples

Example #1

File: child_supervision.cpp Project: abtink/openthread

void ChildSupervisor::SendMessage(Child &aChild)
{
    Message *message = NULL;
    uint8_t  childIndex;

    VerifyOrExit(aChild.GetIndirectMessageCount() == 0);

    VerifyOrExit(message != NULL);

    // Supervision message is an empty payload 15.4 data frame.
    // The child index is stored here in the message content to allow
    // the destination of the message to be later retrieved using
    // `ChildSupervisor::GetDestination(message)`.

    childIndex = Get<ChildTable>().GetChildIndex(aChild);
