PetscOptionsInsertFile

 Inserts options into the database from a file.

Synopsis

#include "petscsys.h"   
PetscErrorCode  PetscOptionsInsertFile(MPI_Comm comm,PetscOptions options,const char file[],PetscBool require)
Collective on MPI_Comm

Input Parameter

comm - the processes that will share the options (usually PETSC_COMM_WORLD)
options - options database, use NULL for default global database
file - name of file
require - if PETSC_TRUE will generate an error if the file does not exist

Notes: Use # for lines that are comments and which should be ignored.

Usually, instead of using this command, one should list the file name in the call to PetscInitialize(), this insures that certain options such as -log_summary or -malloc_debug are processed properly. This routine only sets options into the options database that will be processed by later calls to XXXSetFromOptions() it should not be used for options listed under PetscInitialize().
