# SNESGetLinearSolveIterations
Gets the total number of linear iterations used by the nonlinear solver. 
## Synopsis
```
#include "petscsnes.h"  
PetscErrorCode SNESGetLinearSolveIterations(SNES snes, PetscInt *lits)
```
Not Collective


## Input Parameter

- ***snes -*** `SNES` context



## Output Parameter

- ***lits -*** number of linear iterations





## Notes
This counter is reset to zero for each successive call to `SNESSolve()` unless `SNESSetCountersReset()` is used.

If the linear solver fails inside the `SNESSolve()` the iterations for that call to the linear solver are not included. If you wish to count them
then call `KSPGetIterationNumber()` after the failed solve.
