PetscViewerASCIIOpenWithFILE#

Given an open file creates an PETSCVIEWERASCII viewer that prints to it.

Synopsis#

#include "petscviewer.h"   
PetscErrorCode PetscViewerASCIIOpenWithFILE(MPI_Comm comm, FILE *fd, PetscViewer *lab)

Collective

Input Parameters#

  • comm - the communicator

  • fd - the FILE pointer

Output Parameter#

Notes#

This PetscViewer can be destroyed with PetscViewerDestroy(), but the fd will NOT be closed.

If a multiprocessor communicator is used (such as PETSC_COMM_WORLD), then only the first processor in the group uses the file. All other processors send their data to the first processor to print.

Fortran Notes#

Use PetscViewerASCIIOpenWithFileUnit()
