Set parameter when call dll

[alex.]

I have a dll function which contain a function as:

1.      TEST1_API int Init(int plen);// [in] plenDescription: to set maxmum buffer length (int byte); called before using any function of dll;Return value: -1 – buffer initial failed; 1 – buffer initial success

When I test it in LV, it popup message said I need to set parameters as the screenshot.

May I know how to do it.

Thanks.

Welcome!

Take a note, that the similar message appear, if you have defined parameters, but then function name was changed.

You also appear to have some function name decoration going on. I assume you have an export table?

Thanks, I tried to add the parameter, but it report a error and the function names looks strange, not like you shown.

Any where need to setup or the any name decoration I need to do. May I know how can I do it.
