Gets the current iteration number. If the call to <A HREF="../EPS/EPSSolve.html#EPSSolve">EPSSolve</A>() is complete, then it returns the number of iterations carried out by the solution method.

During the i-th iteration this call returns i-1. If <A HREF="../EPS/EPSSolve.html#EPSSolve">EPSSolve</A>() is
complete, then parameter "its" contains either the iteration number at
which convergence was successfully reached, or failure was detected.
Call <A HREF="../EPS/EPSGetConvergedReason.html#EPSGetConvergedReason">EPSGetConvergedReason</A>() to determine if the solver converged or
failed and why.
