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