About the GX to call C code in a DLL

tedye

Hello,
I want to use a GX to call the C code DLL of my proprietary filter,.
I know that to use the GX call C funtion in DLL is GX--call GX wrapper--call my DLL.
And I design the GX just like the lowpass GX, but I don't know how to transmit the INT or DOUBLE argument from the GX to the GX wrapper?
For example,in the lowpass GX,I want to know how to transmit the Cutoff wavelength from the gx to the GX wrapper and the GX wrapper to my function in DLL?

Best regards.
