KSPGetApplicationContext#

Gets the user-defined context for the linear solver set with KSPSetApplicationContext()

Synopsis#

#include "petscksp.h" 
PetscErrorCode KSPGetApplicationContext(KSP ksp, PeCtx ctx)

Not Collective

Input Parameter#

ksp - KSP context

Output Parameter#

ctx - a pointer to the 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 KSPGetApplicationContext
    Subroutine KSPGetApplicationContext(ksp,ctx,ierr)
  #include <petsc/finclude/petscksp.h>
      use petscksp
      KSP ksp
      type(tUsertype), pointer :: ctx
      PetscErrorCode ierr
    End Subroutine
  End Interface KSPGetApplicationContext

The prototype for ctx must be

  type(tUsertype), pointer :: ctx

Level#
