I have a program written in Fortran, and some variables are defined in .inc files. I want to call self-written C function from the Fortran program, and this function must read and write data to the variables. How should I let know C function about this variables? I'm using gcc and gfortran as compilers.

Often what's found in "INC files" are declarations for common blocks. Is that your situation? – IanH Nov 12 '13 at 18:59
