int tfWaitXmitInterface (ttUserInterface interfaceHandle);


Function Description

If there is no data ready to be transmitted, then it waits. The caller should then call tfXmitInterface() when this call completes successfully.


Note Note: tfWaitXmitInterface() can only be used when there is a separate transmit task.


Parameters

  • interfaceHandle
    The interface handle for the device to which to send the data.


Returns

  • TM_ENOERROR
    Success.
  • TM_ENOBUFS
    Insufficient memory to complete the operation.
