Hi guys,

I have a main program, in C (which contains the "main" ). I have some
subroutine in Fortran. There is no problems there since I know how to call
back Fortran in a C program, using the following:

in .c where I want my fortran sub to be called:
extern void __stdcall ice(long*);
...
int main(void)
{
...
int anInteger = 0;
ice(&anInteger);
... return(0);
}

in the fortran:
SUBROUTINE ice(theInt);
INTEGER theInt
...
END

ok, but the question is, how to call a C function, within a fortran
subroutine, previously called by the main "C" routine? That is of great
importance since many infos are within the C code and I want some routine in
Fortran to reach those infos at run time.

thanks a lot

Mathieu
