PetscViewerRegisterDynamic

Adds a method to the Krylov subspace solver package.

int PetscViewerRegisterDynamic(char *name_solver,char *path,char *name_create,int (*routine_create)(PetscViewer))

Not Collective

	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

PetscViewerRegisterDynamic() may be called multiple times to add several user-defined solvers.

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

   PetscViewerRegisterDynamic("my_viewer_type",/home/username/my_lib/lib/libO/solaris/mylib.a,
               "MyViewerCreate",MyViewerCreate);

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

    PetscViewerSetType(ksp,"my_viewer_type")

or at runtime via the option

    -viewer_type my_viewer_type
