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

Synopsis

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

Input Parameters

comm - the communicator
fd - the FILE pointer

Output Parameter

lab -the PetscViewer to use with the specified file
