Question

What kind of variable should I initialize and how do I do it?

For example

byte[][][] data = ?????;

The function is from LibJpeg.NET library. The function definition is

Int32 jpeg_read_raw_data (
    Byte[][][] data,
    Int32 max_lines
)

There is no good documentation for this function, so I don’t know what to send it, but I want to try to send something and see what the function will return.

The problem is that I don’t know how to call it.

After a short look into the sources of LibJpeg.NET it looks like you should initialize the first dimension of the data array with the number of scan lines:

byte[][][] data = new byte[max_lines][][];

The rest of the array is filled when reading the raw data.

I’m not too familiar with that API so I don’t know how you would get the number of scan lines though.
