PETSc version 3.15.5
PetscRandomRegister
Adds a new PetscRandom component implementation 
Synopsis
#include "petscsys.h" 
PetscErrorCode  PetscRandomRegister(const char sname[], PetscErrorCode (*function)(PetscRandom))
Not Collective
Input Parameters
|  | name | - The name of a new user-defined creation routine | 
|  | create_func | - The creation routine itself | 
Notes
PetscRandomRegister() may be called multiple times to add several user-defined randome number generators
Sample 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
Notes
For an example of the code needed to interface your own random number generator see
