Pass NULL in any argument that is not requested.
<P>
The C macros SLEPC_VERSION_MAJOR, SLEPC_VERSION_MINOR, SLEPC_VERSION_SUBMINOR,
SLEPC_VERSION_RELEASE provide the information at compile time. This can be used to confirm
that the shared library being loaded at runtime has the appropriate version updates.

This function can be called before <A HREF="../sys/SlepcInitialize.html#SlepcInitialize">SlepcInitialize</A>().
