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

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