PetscRandomRegister#
Adds a new PetscRandom implementation
Synopsis#
#include "petscsys.h" 
PetscErrorCode PetscRandomRegister(const char sname[], PetscErrorCode (*function)(PetscRandom))
Not Collective, No Fortran Support
Input Parameters#
- sname - The name of a new user-defined creation routine 
- function - The creation routine 
Notes#
PetscRandomRegister() may be called multiple times to add several user-defined random number generators
For an example of the code needed to interface your own random number generator see src/sys/random/impls/rand/rand.c
Example Usage#
    PetscRandomRegister("my_rand",  MyPetscRandomtorCreate);
Then, your random type can be chosen with the procedural interface via
    PetscRandomCreate(MPI_Comm, PetscRandom *);
    PetscRandomSetType(PetscRandom,"my_random_name");
or at runtime via the option
    -random_type my_random_name
