Detailed Description

This class provides all secure random rutines.

Constructor & Destructor Documentation

Rand::Rand ( )

The Rand constructor generate a new random seed.

float Rand::genSeed ( )

Parameters

Generate a new seed using some black magic

seed = (float)( (usecs.tv_usec + getpid()) ^ (int(Rand::getTicks()) << 16) / 10000 );

char Rand::getChar ( )

Parameters

Get	a random char

char Rand::getLetter ( )

Get a random [A-Z] char.

int Rand::getNumber ( int a )

Get a random number.

Parameters

a	number len

float Rand::getSeed ( )

Random sed getter.

unsigned long Rand::getTicks ( )

This function get the tick number from the CPU.

In ix86 and amd64 uses RDTSC to get the low ticks value.
In ARMv6 and ARMv7 currently uses a gettimeofday()

void Rand::setSeed ( float a )

Random seed setter.

Parameters

a	The new seed
