PCRegisterDynamic

Adds a method to the preconditioner package.

Synopsis

PetscErrorCode PCRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(PC))

Not collective

Input Parameters

	name_solver	- name of a new user-defined solver
	path	- path (either absolute or relative) the library containing this solver
	name_create	- name of routine to create method context
	routine_create	- routine to create method context

Notes

PCRegisterDynamic() may be called multiple times to add several user-defined preconditioners.

If dynamic libraries are used, then the fourth input argument (routine_create) is ignored.

Sample usage

   PCRegisterDynamic("my_solver","/home/username/my_lib/lib/libO/solaris/mylib",
              "MySolverCreate",MySolverCreate);

Then, your solver can be chosen with the procedural interface via

    PCSetType(pc,"my_solver")

or at runtime via the option

    -pc_type my_solver

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 PCRegister() instead
