[petsc-users] PetscOptionsGetString Not Finding Option

     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?
