safe_shared_memory_alloc_bool Subroutine

private subroutine safe_shared_memory_alloc_bool(this, size, name)

Wrapper for shared_allocate_mpi that tests if the pointer is associated @param[out] win MPI shared memory window for internal MPI usage @param[out] ptr pointer to be allocated, on return points to a shared memory segment of given size @param[in] size size of the memory segment to be allocated
