PCShellSetContext#

sets the context for a shell PC that can be accessed with PCShellGetContext()

Synopsis#

#include "petscpc.h" 
PetscErrorCode PCShellSetContext(PC pc, void *ctx)

Logically Collective

Input Parameters#

  • pc - the PC of type PCSHELL

  • ctx - the context

Notes#

This routine is intended for use within the various user-provided routines set with, for example, PCShellSetApply()

One should also provide a routine to destroy the context when pc is destroyed with PCShellSetDestroy()

Fortran Notes#

To use this from Fortran you must write a Fortran interface definition for this function that tells Fortran the Fortran derived data type that you are passing in as the ctx argument.
