<remarks>
|
|
<para>
|
|
The input string <paramref name="p" /> must have a terminating

null. The definition of "terminating null" is fluid in this

|
context, since the size of a terminating null depends upon the
|
|
encoding specified.
|
|
</para>
|
|
<para>
|
|
A terminating null is a single byte containing the value
|
|
<c>0x00</c> if <paramref name="encoding" /> is one of the
|
|
following encodings:
|
|
<see cref="T:System.Text.ASCIIEncoding" />,
|
|
<see cref="T:System.Text.UTF8Encoding" />,
|
|
<see cref="T:System.Text.UTF7Encoding" />, or

<see cref="T:Mono.Unix.UnixEncoding" />.

</para>
|
|
<para>
|

A terminating null is the <see cref="T:System.Int16" /> value
|
|
<c>0x0000</c> if <paramref name="encoding" /> is
|
|
<see cref="T:System.Text.UnicodeEncoding" />.
|
|
</para>
|
|
<para>

Otherwise, the terminating null must consist of a sequence of
|

<see cref="M:System.Text.Encoding.GetMaxByteCount" />(1) bytes
|
|
having the value <c>0x00</c>.
|
|
<block subset="none" type="note">
|
|
This potentially plays havoc with multi-byte encodings, as many
|
|
multi-byte encodings would only use a single byte for the

|
terminating null, and not the maximum possible number of bytes
|
|
used for encoding any character to be used for the terminating
|

null.
