If I have a Fortran subroutine which takes a Fortran IO Unit as one of its parameters (for printing debug information to), and this function is compiled into a shared library, how do I correctly call this function from C?
! An example subroutine that I want to call from C: subroutine hi(unit) integer :: unit write(unit,*) "hello" end subroutine ! example call site in Fortran program main call hi(6) end
I am interested in how these unit numbers relate to file descriptors.
