This counter is reset to zero for each successive call to <A HREF="../SNES/SNESSolve.html#SNESSolve">SNESSolve</A>() unless <A HREF="../SNES/SNESSetCountersReset.html#SNESSetCountersReset">SNESSetCountersReset</A>() is used.
<P>
If the linear solver fails inside the <A HREF="../SNES/SNESSolve.html#SNESSolve">SNESSolve</A>() the iterations for that call to the linear solver are not included. If you wish to count them
then call <A HREF="../KSP/KSPGetIterationNumber.html#KSPGetIterationNumber">KSPGetIterationNumber</A>() after the failed solve.
