Definition in file random.h.
| void RandInit | ( | ) |
Initalizes the random number generator, or opens access to an existing one.
On non-Windows systems, this will attempt to open /dev/urandom. If it cannot be opened or if the program is compiled on Windows, it will fallback on the ANSI C pseudo random number generator.

| Uint32 RandNum | ( | ) |
Obtains a random number.
If the ANSI C pseudo random number generator is being used, it will be called twice and place the first result in the upper 16-bits, and the second result in the lower 16-bits. This will normally result in 30-bits of random data. If /dev/urandom is being used, 4 bytes will be read and placed in the integer for 32-bits of randomness.
