PetscViewerASCIIStdoutSetFileUnit

sets PETSC_VIEWER_STDOUT_() to write to a Fortran IO unit

Synopsis

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

Input Parameter

• unit - the unit number

Output Parameter

• ierr - the error code

Notes

Can be called before PetscInitialize()

Immediately changes the output for all PETSC_VIEWER_STDOUT_() viewers

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() and PetscViewerASCIIWORLDSetFILE() could be added
