# KSPGetTotalIterations

Gets the total number of iterations this KSP object has performed since was created, counted over all linear solves

### Synopsis

    #include "petscksp.h"
    PetscErrorCode  KSPGetTotalIterations(KSP ksp,PetscInt *its)

Not Collective

### Input Parameters

ksp -the iterative context

### Output Parameters

its -total number of iterations

### Notes

Use KSPGetIterationNumber() to get the count for the most recent solve only If this is called within a linear solve (such as in a KSPMonitor routine) then it does not include iterations within that current solve
