How do I return a pointer for the Aardvark API?

I'm using Total Phase's Aardvark USB Adapter and I'm wondering how to return a pointer?

I'm trying to use:

dataOut = [0 18];
dataTargetID = NET.createArray('System.Byte',19);
TotalPhase.AardvarkApi.aa_i2c_write_read(aard_device, slaveAddress, ... TotalPhase.AardvarkI2cFlags.AA_I2C_NO_FLAGS, 2, dataOut, write_count, 19, dataTargetID, read_count);

and I want to get write_count and read_count. From the user manual: http://www.totalphase.com/support/articles/200468316-Aardvark-Adapter-User-Manual#s5.5

it says the input is a unsigned short pointer?

I've tried:

    read_count = NET.createArray('System.UInt16',1);
    read_count = libpointer('UInt16');
    read_count = 0;

but I always get the error:

    No method 'aa_spi_slave_read' with matching signature found for class
    'TotalPhase.AardvarkApi'.

Thanks!

libpointer objects are only for use with the calllib command. No .net or other method will recognize them.

Use 'methodsview TotalPhase.AardvarkApi' to see what aa_write_read returns. The read_count and write_count is returned so passing by reference isn't needed

I have the oppositie problem- the counts are simply returned but the values are passed by reference. Did your code successfully return the values?
