============== Random numbers ============== Function overview ================= .. code-block:: c #include int HX_rand(void); unsigned int HX_irand(unsigned int min, unsigned int max); double HX_drand(double min, double max); ``HX_rand`` Retrieve the next random number. ``HX_irand`` Retrieve the next random number and fold it such that *min <= n < max*. ``HX_drand`` Retrieve the next random number and fold it such that *min <= n < max*. Implementation information ========================== ``/dev/urandom`` will be used to seed the libc-level number generator. ``/dev/random`` is not used on Linux because it may block during read, and /dev/urandom is just as good when there is entropy available. If you need definitive PRNG security, perhaps use one from a crypto suite such as OpenSSL.
