MCH3401 removal

Hi,
I have a wrapper around rslvsp so that I can access objects in QTEMP.
I am basically doing an "IF Object Exists" test in an RPG IV program by
calling a C function that evokes rslvsp.
When the object does not exist, a signal handler is evoked and I return a
*NULL value to the caller. When it does exist, I return the system pointer.
Where I'm lost is how to filter/remove the MCH3401 message so that the user
doesn't see it in their joblog. I want to do this because they may be
calling this procedure 1000's of times and that would just clutter things
up.
Is there a way to filter out messages without doing a dynamic call to one of
the QMHxxxxx message APIs?
