Returns the context for the Picard iteration

Synopsis#

#include "petscsnes.h"  
PetscErrorCode SNESGetPicard(SNES snes, Vec *r, PetscErrorCode (**f)(SNES, Vec, Vec, void *), Mat *Amat, Mat *Pmat, PetscErrorCode (**J)(SNES, Vec, Mat, Mat, void *), void **ctx)

Not Collective, but Vec is parallel if SNES is parallel. Collective if Vec is requested, but has not been created yet.
