PCGetApplicationContext#

Synopsis#

#include "petscpc.h" 
PetscErrorCode PCGetApplicationContext(PC pc, PeCtx ctx)

Not Collective

Input Parameter#

• pc - PC context

Output Parameter#

• ctx - user context

Fortran Notes#

This only works when the context is a Fortran derived type (it cannot be a PetscObject) and you must write a Fortran interface definition for this function that tells the Fortran compiler the derived data type that is returned as the ctx argument. For example,

  Interface PCGetApplicationContext
    Subroutine PCGetApplicationContext(pc,ctx,ierr)
  #include <petsc/finclude/petscpc.h>
      use petscpc
      PC pc
      type(tUsertype), pointer :: ctx
      PetscErrorCode ierr
    End Subroutine
  End Interface PCGetApplicationContext

The prototype for ctx must be

  type(tUsertype), pointer :: ctx
