51 Notes:
52 The C macros PETSC_VERSION_MAJOR, PETSC_VERSION_MINOR, PETSC_VERSION_SUBMINOR, PETSC_VERSION_RELEASE provide the information at
53 compile time. This can be used to confirm that the shared library being loaded at runtime has the appropriate version updates.
54
55 This function can be called before PetscInitialize()
