NAME

vllrancw - return vector of uniformly-distributed pseudorandom 64-bit unsigned integers

SYNOPSIS

cc [ flags ] -I/usr/local/include file(s) -L/usr/local/lib -lmcw [ ... ]

#include <mathcw.h>

extern void vllrancw (int n, UINT_LEAST64_T u[]);


DESCRIPTION

Return a vector of n uniformly-distributed pseudorandom 64-bit unsigned integers. The generator state is kept internally to simplify the user interface. However, this is not safe in multithreaded programs. For them, use the reentrant generator routines instead, identified by the suffix _r. The reentrant routines also make possible families of independent generators within the same program. The generator is Marsaglia's KISS generator, which has a long period of about 2**123 (approximately 10**37), and has passed several difficult tests of randomness, including Marsaglia's Diehard Battery test suite, and the Marsaglia/Tsang tuftest suite. The generated values span the range (0, 2**64 - 1); neither endpoint is reachable.

RETURN VALUES

Vector u[] of pseudorandom integers.

ERRORS

None.
