FPGA C API feature parity with Labview FPGA modul ?

Highlighted

 

Hi there,

 

I have a question regarding the behaviour of FIFO.Stop method when using the FPGA C API.

 

 

 

* The documentation for the FIFO.Stop (Invoke Method, FPGA modul) explicitly states this :

 

"Stops the DMA data transfer between the FPGA target and the host computer. This method deletes all data from the host memory and FPGA parts of the FIFO. "

http://zone.ni.com/reference/en-XX/help/371599P-01/lvfpgahost/fpga_method_fifo_stop/

 

 

* However the documentation for the FPGA C API equivalent function NiFpga_StopFifo states only this

 

"Stops a FIFO. This method is optional."

NiFpga_Status NiFpga_StopFifo(NiFpga_Session session, uint32_t fifo)

source : FPGA C API help file. 

https://zone.ni.com/reference/en-XX/help/372928H-01/capi/fpgac/

 

 

My concerns:

 

FPGA modul's FIFO.Stop method deletes all data from the host memory and FPGA parts of the FIFO.

I would like to know if this is the case also when using the FPGA C API?

In fact I would need the functionality of deleting the data also from FPGA part.

 

 

My questions.

 

1. Is there already a feature parity between FPGA modul and FPGA C API or the problem

is only the FPGA C API help file is very old from 2014 and not updated ?

2. Any plans to update this help file?

 

 

Thank you for any clarifications. 

Mike
