PetscInitializeFortran

 Routine that should be called soon AFTER the call to PetscInitialize() if one is using a C main program that calls Fortran routines that in turn call PETSc routines.

Synopsis

PetscErrorCode PetscInitializeFortran(void)
Collective on PETSC_COMM_WORLD

Notes

PetscInitializeFortran() initializes some of the default viewers, communicators, etc. for use in the Fortran if a user's main program is written in C. PetscInitializeFortran() is NOT needed if a user's main program is written in Fortran; in this case, just calling PetscInitialize() in the main (Fortran) program is sufficient.
