<para>
Find the position of the first bit set in @mask, searching from (but not
including) @nth_bit upwards. Bits are numbered from 0 (least significant)
to sizeof(#gulong) * 8 - 1 (31 or 63, usually). To start searching from the
0th bit, set @nth_bit to -1.
</para>
@mask: a #gulong containing flags.
@nth_bit: the index of the bit to start the search from.
@Returns: the index of the first bit set which is higher than @nth_bit.
<!-- ##### FUNCTION g_bit_nth_msf ##### -->
<para>
Find the position of the first bit set in @mask, searching from (but not
including) @nth_bit downwards. Bits are numbered from 0 (least significant)
to sizeof(#gulong) * 8 - 1 (31 or 63, usually). To start searching from the
last bit, set @nth_bit to -1 or GLIB_SIZEOF_LONG * 8.
</para>
@mask: a #gulong containing flags.
@nth_bit: the index of the bit to start the search from.
@Returns: the index of the first bit set which is lower than @nth_bit.

@number: a guint.
@Returns: the number of bits used to hold @number.
<!-- ##### FUNCTION g_spaced_primes_closest ##### -->
<para>
Gets the smallest prime number from a built-in array of primes which
is larger than @num. This is used within GLib to calculate the optimum
size of a #GHashTable.
</para>
<para>
The built-in array of primes ranges from 11 to 13845163 such that
each prime is approximately 1.5-2 times the previous prime.
</para>
@num: a #guint.
@Returns: the smallest prime number from a built-in array of primes which is
larger than @num.
