78    PetscErrorCode PetscViewerRegisterDynamic(char *name_solver,char *path,char *name_create,PetscErrorCode (*routine_create)(PetscViewer))
79 
80    Not Collective
81 
82    Input Parameters:
83 +  name_solver - name of a new user-defined solver
84 .  path - path (either absolute or relative) the library containing this solver
85 .  name_create - name of routine to create method context
86 -  routine_create - routine to create method context
87 
88    Level: developer
89 
90    Notes:
91    PetscViewerRegisterDynamic() may be called multiple times to add several user-defined solvers.
92 
93    If dynamic libraries are used, then the fourth input argument (routine_create)
94    is ignored.
95 
96    Sample usage:
97 .vb
98    PetscViewerRegisterDynamic("my_viewer_type",/home/username/my_lib/lib/libO/solaris/mylib.a,
99                "MyViewerCreate",MyViewerCreate);
100 .ve
101 
102    Then, your solver can be chosen with the procedural interface via
103 $     PetscViewerSetType(ksp,"my_viewer_type")
104    or at runtime via the option
105 $     -viewer_type my_viewer_type
