BM_WriteMultipleCanMessage
Write multiple CAN messages to the given channel.
BMAPI BM_StatusTypeDef BM_WriteMultipleCanMessage (BM_ChannelHandle handle, const BM_CanMessageTypeDef msg[], uint32_t *nmessages, uint32_t _channel[], int timeout, uint32_t timestamp[])Parameters
Section titled “Parameters”| Direction | Name | Description |
|---|---|---|
| [in] | handle |
Handle to the channel to write to. |
| [in] | msg |
A caller-allocated buffer to hold the CAN message array input, see BM_CanMessageTypeDef for details. |
| [in,out] | nmessages |
Number of written messages, user shall initialize this param with the size (in messages) of the data buffer. |
| [in] | _channel |
The target channel ID to which the message is transmitted, starting from zero. This parameter is reserved for future, always 0 now, or simply pass NULL into the API. |
| [in] | 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 BMAPI internal buffer and return immediately, then receive TXCMPLT event over BM_Read() later. |
| [out] | timestamp |
The device local high precision timestamp array in microseconds, when the message is physically transmitted on the CAN bus, could be NULL if not required. |
Returns
