40 <p>This function converts a single
<b><font face=
"Courier New">hexstring
</font></b> value to a single
<b><font face=
"Courier New">bitstring
</font></b>. The resulting
<b><font
41 face=
"Courier New">bitstring
</font></b> represents the same value as the
<b><font face=
"Courier New">hexstring
</font></b>.
42 <p>For the purpose of this conversion, a
<b><font face=
"Courier New">hexstring
</font></b> should be converted into a
<b><font face=
"Courier New">bitstring
</font></b>, where the hex digits of the
<b><font
43 face=
"Courier New">hexstring
</font></b> are converted in groups of bits as follows:
44 <p>'
0'H -
> '
0000'B,
'
1'H -
> '
0001'B,
'
2'H -
> '
0010'B,
'
3'H -
> '
0011'B,
'
4'H -
> '
0100'B,
'
5'H -
> '
0101'B,
<br>
45 '
6'H -
> '
0110'B,
'
7'H -
> '
0111'B,
'
8'H-

1000'B,
'
9'H -

1001'B,
'A'H -

46 'C'H -

1100'B,
'D'H -
> '
1101'B,
'E'H -
> '
1110'B,
and
'F'H -
> '
1111'B.
47 <p>The consecutive order of the groups of
4 bits in the resulting
<b><font face=
"Courier New">bitstring
</font></b> is the same as the order of hex digits in the
<b><font face=
"Courier New">hexstring
</font></b>.
