CreateFdMessage (FUN)¶

FUNCTION CreateFdMessage : CAA.HANDLE

This function allocates a new Fd message from the data pool of a FD driver and makes it available via its handle hFdMessage. In addition, the function sets the CAN ID, data length and bitrate switching flag of the message. Such a message must either be sent with Write or released with FreeMessage. It can also be duplicated by use of CloneMessage.

Example

See Write.
