PetscOptionsPrefixPush

Designate a prefix to be used by all options insertions to follow.

Synopsis

#include "petscsys.h"   
PetscErrorCode  PetscOptionsPrefixPush(const char prefix[])
Not Collective, but prefix will only be applied on calling ranks

Input Parameter

prefix - The string to append to the existing prefix

Options Database Keys

+ -prefix_push <some_prefix_> - push the given prefix - -prefix_pop - pop the last prefix

Notes

It is common to use this in conjunction with -options_file as in

$ -prefix_push system1_ -options_file system1rc -prefix_pop -prefix_push system2_ -options_file system2rc -prefix_pop

where the files no longer require all options to be prefixed with -system2_.
