<A HREF="../PC/PCRegisterDynamic.html#PCRegisterDynamic">PCRegisterDynamic</A>() may be called multiple times to add several user-defined preconditioners.
<P>
If dynamic libraries are used, then the fourth input argument (routine_create)
is ignored.

<H3><FONT COLOR="#CC3333">Sample usage</FONT></H3>
<PRE>
<A HREF="../PC/PCRegisterDynamic.html#PCRegisterDynamic">PCRegisterDynamic</A>("my_solver","/home/username/my_lib/lib/libO/solaris/mylib",
"MySolverCreate",MySolverCreate);
</PRE>
<P>
Then, your solver can be chosen with the procedural interface via
<pre>
<A HREF="../PC/PCSetType.html#PCSetType">PCSetType</A>(pc,"my_solver")
</pre>
or at runtime via the option
<pre>
-pc_type my_solver
</pre>
<P>
<P>
Notes: ${PETSC_ARCH}, ${PETSC_DIR}, ${PETSC_LIB_DIR}, or ${any environmental variable}
occuring in pathname will be replaced with appropriate values.
If your function is not being put into a shared library then use <A HREF="../PC/PCRegister.html#PCRegister">PCRegister</A>() instead
