Symbian Random Number

No matter what programs are developed, especially games like card games and puzzles, and games like Tetris,
Random number generator is essential. In the standard C language, seed () and rand () are used to generate seeds and values.
In the Symbian platform, what method is used? The following is an example.

TTime thetime (kaknexnoteinitializetime );
Thetime. universaltime ();
Tint64 randseed (thetime. int64 (); // uses the time to initialize the Random Seed.
Tint number (Math: rand (randseed) % kaknexnoterandomnumberrange); // This is called
The generated result is placed in number.

Returns a random number between two numbers.

Tint getrangnum (tint startnum, tint endnum)
{
TTime thetime (startnum );
Thetime. universaltime ();
Tint64 randseed (thetime. int64 ());
Tint number (startnum + Math: rand (randseed) % (endnum-startnum ));

Return number;

}
