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