# TaoGetSolutionStatus
Get the current iterate, objective value, residual, infeasibility, and termination from a `Tao` object 
## Synopsis
```
#include "petsctao.h" 
PetscErrorCode TaoGetSolutionStatus(Tao tao, PetscInt *its, PetscReal *f, PetscReal *gnorm, PetscReal *cnorm, PetscReal *xdiff, TaoConvergedReason *reason)
```
Not Collective


## Input Parameter

- ***tao -*** the `Tao` context



## Output Parameters

- ***iterate -*** the current iterate number (>=0)
- ***f -*** the current function value
- ***gnorm -*** the square of the gradient norm, duality gap, or other measure indicating distance from optimality.
- ***cnorm -*** the infeasibility of the current solution with regard to the constraints.
- ***xdiff -*** the step length or trust region radius of the most recent iterate.
- ***reason -*** The termination reason, which can equal `TAO_CONTINUE_ITERATING`





## Notes
Tao returns the values set by the solvers in the routine `TaoMonitor()`.

If any of the output arguments are set to `NULL`, no corresponding value will be returned.
