44    PetscDrawRegisterDynamic - Adds a method to the Krylov subspace solver package.

47    PetscErrorCode PetscDrawRegisterDynamic(const char *name_solver,const char *path,const char *name_create,PetscErrorCode (*routine_create)(PetscDraw))
48 
49    Not Collective
50 
51    Input Parameters:
52 +  name_solver - name of a new user-defined solver
53 .  path - path (either absolute or relative) the library containing this solver
54 .  name_create - name of routine to create method context
55 -  routine_create - routine to create method context
56 
57    Level: developer
58 
59    Notes:
60    PetscDrawRegisterDynamic() may be called multiple times to add several user-defined solvers.
61 
62    If dynamic libraries are used, then the fourth input argument (routine_create)
63    is ignored.
64 
65    Sample usage:
66 .vb
67    PetscDrawRegisterDynamic("my_draw_type",/home/username/my_lib/lib/libO/solaris/mylib.a,
68                "MyDrawCreate",MyDrawCreate);
69 .ve
70 
71    Then, your solver can be chosen with the procedural interface via
72 $     PetscDrawSetType(ksp,"my_draw_type")
73    or at runtime via the option
74 $     -draw_type my_draw_type
