@deftypefn {C Function} void scm_to_mpz (SCM val, mpz_t rop)
Assign @var{val} to the multiple precision integer @var{rop}.
@var{val} must be an exact integer, otherwise an error will be
signalled. @var{rop} must have been initialized with @code{mpz_init}
before this function is called. When @var{rop} is no longer needed
the occupied space must be freed with @code{mpz_clear}.
