For examples, I got errors such as too few arguments in function call, but some errors were about the new functionality in the latest version. Does anyone know about 3.4.4 functions corresponding to KSPSetReusePreconditioner() and MatMumpsSetIcntl()? In advance, thanks for your comments.

  Those simply did not exist at that time. You can get the effect of KSPSetReusePreconditioner() by passing the flag SAME_PRECONDITIONER as the final argument to KSPSetOperators().
