Hell Hong,
Is there a way to directly query the options database to get
the value of Petsc options? This is related to the discussion here:
http://lists.mcs.anl.gov/pipermail/petsc-dev/2015-July/017944.html . I
though PetscOptionsGetString and PetscOptionsSetValue would provide this
capability, but now it seems like petsc options cannot be accessed.

Either call KSPSetPCSide() or change
const char name[] = "-ksp_pc_side"
to a non-petsc option name, e.g., "-my_ksp_pc_side".

Hello,
I am trying to use PetscOptionsGetString to retrieve the value
of an option in the options database, but the value returned in
the last argument indicates the option was not found. In the
attached code (a modified version of ksp example 2), the string
"-ksp_pc_side" is passed in as the argument name. If I run the code as
./jc2 -pc_type ilu -ksp_pc_side right
I get the output:
option -ksp_pc_side was found
from line 71 of the file. Petsc does not complain of unused
options when the program finishes. Am I using this function
incorrectly?
