The variable <spanclass="parameter">state</span> must be initialized by calling one of the <spanclass="code">gmp_randinit</span>
functions (<ahref="https://gmplib.org/manual/Random-State-Initialization.html#Random-State-Initialization">GNU MP - Random State Initialization</a>) before invoking this function.
</p><p>
The random number functions of GMP come in two groups; older function that rely on a global state,
and newer functions that accept a state parameter that is read and modified.
Please see the <ahref="https://gmplib.org/manual/Random-Number-Functions.html#Random-Number-Functions">GNU MP - Random Number Functions</a>
for more information on how to use and not to use random number functions.
