hi,this is ravikiran,

i am using jawin to call thirdparty dlls.

i have no idea how to make a call to the above method, so that i can get
the content of the pointer that the method is returning.

can any one help me how to do this in jawin. i am new to jawin and i didnt
find any examples that suite my requiements.

thanks in advance.
