VecRegisterDynamic

Adds a new vector component implementation

Synopsis

PetscErrorCode VecRegisterDynamic(const char *name, const char *path, const char *func_name, PetscErrorCode (*create_func)(Vec))

Not Collective

Input Parameters

	name	- The name of a new user-defined creation routine
	path	- The path (either absolute or relative) of the library containing this routine
	func_name	- The name of routine to create method context
	create_func	- The creation routine itself

Notes

VecRegisterDynamic() may be called multiple times to add several user-defined vectors

If dynamic libraries are used, then the fourth input argument (routine_create) is ignored.

Sample usage

    VecRegisterDynamic("my_vec","/home/username/my_lib/lib/libO/solaris/libmy.a", "MyVectorCreate", MyVectorCreate);

Then, your vector type can be chosen with the procedural interface via

    VecCreate(MPI_Comm, Vec *);
    VecSetType(Vec,"my_vector_name");

or at runtime via the option

    -vec_type my_vector_name

Notes: $PETSC_ARCH occuring in pathname will be replaced with appropriate values. If your function is not being put into a shared library then use VecRegister() instead
