17    Notes: The DMDACreate() based object and the DMCompositeCreate() based object are examples of DMs
18 
19           Though the DM objects require the petscsnes.h include files the DM library is
20     NOT dependent on the SNES or KSP library. In fact, the KSP and SNES libraries depend on
21     DM. (This is not great design, but not trivial to fix).

60   DMRegisterDynamic - Adds a new DM component implementation
61 
62   Synopsis:
63   PetscErrorCode DMRegisterDynamic(const char *name,const char *path,const char *func_name, PetscErrorCode (*create_func)(DM))
64 
65   Not Collective
66 
67   Input Parameters:
68 + name        - The name of a new user-defined creation routine
69 . path        - The path (either absolute or relative) of the library containing this routine
70 . func_name   - The name of routine to create method context
71 - create_func - The creation routine itself
72 
73   Notes:
74   DMRegisterDynamic() may be called multiple times to add several user-defined DMs
75 
76   If dynamic libraries are used, then the fourth input argument (routine_create) is ignored.
77 
78   Sample usage:
79 .vb
80     DMRegisterDynamic("my_da","/home/username/my_lib/lib/libO/solaris/libmy.a", "MyDMCreate", MyDMCreate);
81 .ve
82 
83   Then, your DM type can be chosen with the procedural interface via
84 .vb
85     DMCreate(MPI_Comm, DM *);
86     DMSetType(DM,"my_da_name");
87 .ve
88    or at runtime via the option
89 .vb
90     -da_type my_da_name
91 .ve
92 
93   Notes: $PETSC_ARCH occuring in pathname will be replaced with appropriate values.
94          If your function is not being put into a shared library then use DMRegister() instead
