PetscViewerASCIIWORLDSetFileUnit#

sets PETSC_VIEWER_STDOUT_WORLD to write to a Fortran IO unit

Synopsis#

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

Input Parameter#

  • unit - the unit number

Output Parameter#

  • ierr - the error code

Notes#

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

Fortran Note#

Only for Fortran

Developer Note#

PetscViewerASCIIWORLDSetFilename() could be added in the future
