Function BM_WriteCanMessage 

Source 
pub unsafe extern "C" fn BM_WriteCanMessage(
    channel_handle: *const c_void,

    reserved: c_int,
    timeout: c_int,
    timestamp: *mut c_int,
) -> BMStatus
Expand description

Write CAN message to the given channel. Note this function is a simple wrapper to BM_Write, see BM_Write for details.

ยงArguments

  • channel_handle: Handle to the channel to write to.
  • msg: A caller-allocated buffer to hold the CAN message output, see BMCanMessage for details.
  • reserved: The target channel ID to which the message is transmitted, starting from zero. This parameter is reserved for future, always 0 now.
  • timeout: Timeout (in milliseconds) before the message is transmitted successfully to the bus. Set any negative number (i.e. -1) to wait infinitely. Set 0 if you would like to transmit asynchronously: put to BM API internal buffer and return immediately, then receive TXCMPLT event over BM_Read later.
  • timestamp: The device local high precision timestamp in microseconds, when the message is physically transmitted on the CAN bus, could be NULL if not required.

returns: BMStatus
