Deferred-Processing Routine Vector
The DPV block is the template for data that is assembled by the DPR and sent to the application
code as a parameter in a callback routine. The callback routine itself identifies the Section of the
device that caused the DPR processing. Arguments passed via the callback routine identify the
source device (via the
events, that is all the information that the user needs. For others, additional information is needed.
The size of the DPV is kept under sixteen (16) bytes to accommodate the simpler message
passing schemes used by some Operating Systems. The DPV structure definition shown below
defines the format for sTMX_DPV_IO, sTMX_DPV_DS3, sTMX_DPV_FRAMER, and
sTMX_DPV_MAPPER.
Note: The application code is responsible for returning this buffer to the RTOS buffer pool.
