Random numbers
==============
Function overview
=================
.. code-block:: c
#include <libHX/misc.h>
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.
