int _mpn_mod_nonunit(nn_srcptr x, nn_srcptr g, slong gsize, gr_ctx_t ctx)source

Returns the status of a failed inversion of the residue x, given g = \gcd(x, n) in gsize limbs: GR_DOMAIN if x = 0 or the ring does not pretend to be a field; otherwise GR_UNABLE, after recording g as the zero divisor of the context if none was recorded and 1 < g < n.
