Sets bit <parameter>index</parameter> in

<parameter>a</parameter>. <parameter>set_clear</parameter>

Unlike most of the other GMP functions, <function>gmp_setbit</function>
|
|
must be called with a GMP resource that already exists (using
|
|
<function>gmp_init</function> for example). One will not be
|
|
automatically created.
