| snes | - the SNES context | |
| func | - routine to test for convergence | |
| cctx | - [optional] context for private data for the convergence routine (may be PETSC_NULL) | |
| destroy | - [optional] destructor for the context (may be PETSC_NULL; PETSC_NULL_FUNCTION in Fortran) |
PetscErrorCode func (SNES snes,PetscInt it,PetscReal xnorm,PetscReal gnorm,PetscReal f,SNESConvergedReason *reason,void *cctx)
| snes | - the SNES context | |
| it | - current iteration (0 is the first and is before any Newton step) | |
| cctx | - [optional] convergence context | |
| reason | - reason for convergence/divergence | |
| xnorm | - 2-norm of current iterate | |
| gnorm | - 2-norm of current step | |
| f | - 2-norm of function |
