6.2 Buffer Management
All operating systems provide some sort of buffer system, particularly for use in sending and
receiving messages. The following calls, provided by the USER, allow the driver to Get and
Return buffers from the RTOS. It is the USER’s responsibility to create any special resources or
pools to handle buffers of these sizes during the
sysSuni4x622BufferStart call.
Starting Buffer Management: sysSuni4x622BufferStart
This function alerts the RTOS that the time has come to make sure ISV buffers and DPV buffers
are available and sized correctly. This may involve the creation of new buffer pools and it may
involve nothing, depending on the RTOS.
Format
#define sysSuni4x622BufferStart()
Prototype
INT4 sysSuni4x622BufferStart(void)
Inputs
None
Outputs
None
Returns
Success = 0
