Calling a dll from Mathematica

Question

I would like to call the following function from Mathematica

ps3000aOpenUnit
PICO_STATUS ps3000aOpenUnit
(
   short * handle,
   char * serial
)

I define the DLLFunciton in Mathematica:

ps3000OpenUnit =  DefineDLLFunction["ps3000aOpenUnit", "PS3000a.dll", "short", {"short[]", "char[]"}]

I get following error when executing

ps3000OpenUnit[handle, serial]
NET::methodargs: Improper arguments supplied for method named ps3000aOpenUnit.

What is wrong with my code?

Thanx for helping me in advance.

Answer 1

"short" or "char" are in the C programming language data typs.

Try this:

ps3000aOpenUnit = 
  DefineDLLFunction["ps3000aOpenUnit", "ps3000a.dll", "short", {"short*"}];

handle=0;
status = ps3000aOpenUnit[handle];
