[Jprogramming] PInvoke signatures for j.dll

[Greg Borota]

I am successfully marshaling the huge J struct between .NET and j.dll and
no error. It looks like the PInvoke approach is going to work.
I want to create a C wrapper between j.dll and .NET to hold the J singleton
and reduce the marshaling between the two worlds.
Are these document anywhere or could somebody in a few words explain what
each of these functions do:
>dumpbin /EXPORTS j.dll
