PetscViewerASCIIWORLDSetFileUnit#

sets PETSC_VIEWER_STDOUT_WORLD to write to a Fortran IO unit

Synopsis#

#include <petscviewer.h>
void PetscViewerASCIIWORLDSetFileUnit(PetscInt unit, PetscErrorCode ierr)

Must be called before PetscInitialize()

This may not work currently with some viewers that (improperly) use the fd directly instead of PetscViewerASCIIPrintf()

With this option, for example, -log_options results will be saved to the Fortran file

Any process may call this but only the unit passed on the first process is used

Only for Fortran

PetscViewerASCIIWORLDSetFilename() could be added in the future
