The Callback example which comes with CVF shows how to call a VB subroutine from Fortran. However, I need to store the pointer to the VB subroutine and call it from a different module. I understand that I need to use
INTEGER(INT_PTR_KIND()) :: vbcallback
but am not clear on the details. I am new to F9x and am confused by the new features such as 'Interface'. Please could someone post the example modified code show me how? I would really appreciate some help on this.
