Implementation

The GNU C Library, known as glibc, is a free and open source version of the C standard library. If you've used open source software, then you've probably used a program built using this library.

Among the many other tools provided by this library is a Linear Congruential Generator. This generator uses bit masking to return only the last 30 bits of the Seed.

This generator uses the following constants:
