///Usage
///-----
// This section illustrates intended use of this component.

///Example 1: Seeding the Random-Number Generator
/// - - - - - - - - - - - - - - - - - - - - - - -
// System-provided random-number generators generally must be initialized with
// a seed value from which they go on to produce their stream of pseudo-random
// numbers. We can use 'RandomDevice' to provide such a seed.
//
// First, we obtain the results of invoking the random-number generator without
// having seeded it:
//..
int unseededR1 = rand();
int unseededR2 = rand();
//..
// Then, we obtain a random number:
//..
int seed = 0;
int status = bdlb::RandomDevice::getRandomBytes(
reinterpret_cast<unsigned char *>(&seed), sizeof(seed));
ASSERT(0 == status);
ASSERT(0 != seed); // This will fail every few billion attempts...
//..
// Next, we seed the random-number generator with our seed:
//..
srand(seed);
