SDK FAQ集

<p class=inset>Numerous other minor updates.</p>

<p><b>1998.09.27</b></p>
<p class=inset>Added support for changing the TTL value to the <a
href="examples/rawping.html">raw sockets ping program</a>.</p>

<p><b>1998.09.19</b></p>
<p class=inset>Updated the much-neglected <a
href="general.html">Section 1</a>.</p>

<p class=inset>I just discovered that Question 2.12, which I added almost two months
ago, is essentially identical to <a href="newbie.html#q2">Question
2.2</a>. You know your FAQ is getting big when.... Anyway, I nixed
Question 2.12, and used its text in place of the less-well-written
2.2 text.</p>

<p><b>1998.09.07</b></p>
<p class=inset>Added <a href="reviews/index.html">Reviews</a>
section, and wrote the first five book reviews for it.</p>

<p><b>1998.08.23</b></p>
<p class=inset>Added Questions <a href="advanced.html#q16">3.16</a>
and <a href="advanced.html#q17">3.17</a>, regarding issues of "how many
sockets can Winsock handle".</p>

<p><b>1998.08.01</b></p>
<p class=inset>Added <a
href="tutorials/bsd-compatibility.html">Tutorial 3</a>. This material
largely supercedes Questions <a href="advanced.html#q4">3.4</a> and <a
href="advanced.html#q7">3.7</a>, so those items have also changed.</p>

<p class=inset>Turned Questions 2.12 and 2.13 into <a
href="tutorials/corruption.html">Tutorial 4</a>.</p>

<p class=inset>Added a new <a href="newbie.html#q12">Question 2.12</a>, regarding
how to speak various common protocols, like HTTP and FTP.</p>

<p class=inset>Added a new <a href="advanced.html#q4">Question 3.4</a>, regarding
using the SNMP API for accessing the routing table, the ARP table,
the interface list, etc. (It replaces the old Question 3.4, which
was superceded by <a href="tutorials/bsd-compatibility.html">Tutorial
3</a>.)</p>

<p class=inset>Updated several of the entries regarding Windows 98.</p>

<p><b>1998.07.31</b></p>
<p class=inset>Added two more network monitoring
packages to the Debugging portion of the FAQ's <a
href="resources/debugging.html">Resources</a> section.</p>

<p class=inset>Replaced <a href="tutorials/socket-types.html">Tutorial 2</a> with
a new, completely-rewritten version.</p>

<p><b>1998.05.19 and 1998.05.20</b></p>
<p class=inset>Improved the wording of <a
href="advanced.html#q15">Question 3.15</a>.</p>

<p><b>1998.04.28</b></p>
<p class=inset>Fixed a broken link.</p>

<p><b>1998.04.19</b></p>
<p class=inset>Updated <a href="general.html#q9">Question 1.9</a>
and also the <a href="resources/index.html">Resources</a> section.</p>

<p><b>1998.03.23</b></p>
<p class=inset>Added info on structure-padding issues to <a
href="newbie.html#q13">Question 2.13</a>.</p>

<p class=inset>Updated <a href="newbie.html#q10">Question 2.10</a> by removing
the rumor that <tt>FormatMessage</tt> can return error messages for
Winsock error numbers. I have since found out that at best this is
undocumented behavior that only works on one or two of Microsoft's
Winsock implementations. It is by no means a universal thing.</p>

<p><b>1998.03.22</b></p>
<p class=inset>Split <a href="resources/index.html">Resources</a>
page up so that each sub-section has its own page.</a>

<p class=inset>Put the index pages for all the sections with their own directory
in that directory. Now, the HTML file of the same name is just
a redirector. For example, the old examples.html file is now at
examples/index.html, and examples.html automatically forwards you to
the new page.</p>

<p class=inset>Added a few new sniffers to the <a
href="resources/debugging.html">Debugging Resources</a> subsection and
updated most of the the existing entries.</p>

<p><b>1998.02.23</b></p>
<p class=inset>Added a bit of info to the <a
href="examples/getifaces.html">Get Interface List</a> example.</p>

<p class=inset>Added a bug note to the <a href="examples/getmac-netbios.html">Get
MAC Address (NetBIOS version)</a> example.</p>

<p><b>1998.02.16</b></p>
<p class=inset>Added Questions <a href="advanced.html#q13">3.13</a>
and <a href="advanced.html#q14">3.14</a>, concerning raw sockets and
such. Also updated Question <a href="advanced.html#q1">3.1</a> to
reference the new questions for more information.</p>

<p class=inset>Added Question <a href="advanced.html#q15">3.15</a>, concerning the
time and place for turning off the Nagle algorithm.</p>

<p class=inset>Added a number of <a href="glossary.html">glossary</a> entries.</p>

<p><b>1998.02.14</b></p>
<p class=inset>Added the "<a href="examples/rawping.html">raw
ping</a>" example. Also touched up the answers to questions 3.1, 3.2,
3.8 and 1.7.</p>

<p><b>1998.02.02</b></p>
<p class=inset>Added a new tutorial, <i><a
href="tutorials/impatient.html">Winsock for the Impatient</a></i>.</p>

<p class=inset>Updated the Glossary some, mainly the router, gateway and bridge
entries and other related things.</p>

<p><b>1998.02.01</b></p>
<p class=inset>Updated Questions <a href="general.html#q3">1.3</a>
and <a href="general.html#q8">1.8</a> with better Winsock 2 info.</p>

<p class=inset>Expanded <a href="advanced.html#q9">Question 3.9</a> and split it up
into Questions 3.9 through 3.11. Because they are all related, I didn't
put the new questions at the end of the list, as I usually do. Instead,
the old Question 3.10 is now <a href="advanced.html#q12">Question
3.12</a>.</p>

<p class=inset>Had one of those periodic whole-FAQ editing fits, and ended up
re-working a lot of the text, partly for accuracy, partly to fill in
missing detail, and partly just so that it reads better.</p>

<p><b>1998.01.31</b></p>
<p class=inset>Fixed a minor problem in <a
href="advanced.html#q8">Question 3.8</a>.</p>

<p class=inset>Added <a href="newbie.html#q10">Question 2.10</a>, which explains
how to get a readable error message from a Winsock error number.</p>

<p class=inset>Added <a href="newbie.html#q11">Question 2.11</a>, which sheds some
light on the poorly-understood WSAEWOULDBLOCK error.</p>

<p class=inset>Added <a href="newbie.html#q12">Question 2.12</a>, which deals with
the common misconceptions about how TCP "should" work versus how it
actually does work.</p>

<p class=inset>Added <a href="newbie.html#q13">Question 2.13</a>, which talks about
"network order" for integers.</p>

<p class=inset>Added <a href="advanced.html#q9">Question 3.9</a>, which deals with
the behavior of asynchronous sockets in a multithreaded program.</p>

<p class=inset>Added <a href="advanced.html#q10">Question 3.10</a>, which explains how
to tell if the modem is connected on systems with dial-up networking.</p>

<p class=inset>Added the "<a href="examples/getifaces.html">get interfaces</a>"
example.</p>

<p><b>1998.01.19</b></p>
<p class=inset>Added the Tutorials section. The first
one is the information from the way-too-long answer to <a
href="newbie.html#q4">Question 2.4</a>, in article format. The new answer
to Question 2.4 mainly just summarizes the article and points readers
to it for more information.</p>

<p><b>1998.01.17</b></p>
<p class=inset>Added Winsock debugging tools section to <a
href="resources.html#debugging">Resources</a> page.</p>

<p class=inset>Added <a href="newbie.html#q9">Question 2.9</a> to introduce the new
debugging tools section.</p>

<p><b>1998.01.16</b></p>
<p class=inset>Updated the <a href="intro.html">Introduction</a>
page significantly. If you haven't read through it recently, you may want
to give it a quick skim, especially the "future directions" section and
the short-and-unoriginal legal statement.</p>

<p><b>1998.01.12</b></p>
<p class=inset>Updated <a href="newbie.html#q7">Question 2.7</a>
to be correct some misconceptions present in earlier versions.</p>

<p class=inset>Expanded and reorganized the <a href="resources.html">Resources</a>
section significantly.</p>

<p class=inset>Clarified and enhanced <a href="general.html#q6">Question 1.6</a>.</p>

<p><b>1998.01.04</b></p>
<p class=inset>Added the "get MAC address" examples
(<a href="examples/getmac-netbios.html">NetBIOS</a> and <a
href="examples/getmac-rpc.html">RPC</a> methods). Also added <a
href="advanced.html#q8">Question 3.8</a> to introduce those examples.</p>

<p class=inset>Enhanced <a href="advanced.html#q1">Question 3.1</a>, adding more
details about the support for raw sockets on Microsoft and other Winsock
implementations.</p>

<p class=inset>Split Question 2.4 into Questions <a
href="newbie.html#q4a">2.4a</a>, <a href="newbie.html#q4b">2.4b</a>,
and <a href="newbie.html#q4c">2.4c</a>. Each part is now greatly
enhanced, resulting in a much broader and tolerant answer. [Obsolete
<img src="bitmaps/waist-dot.gif" alt="--" width=14 height=6 hspace=2>
see the note for 1998.01.19 for newer info].</p>

<p><b>1997.10.27</b></p>
<p class=inset>Added some info to <a href="advanced.html#q3">Question
3.3</a>. Also changed the wording to use Microsoft's preferred term
"process" rather than "task."</p>

<p><b>1997.10.09</b></p>
<p class=inset>Added the <a href="glossary.html">Glossary</a></p>

<p><b>1997.10.07</b></p>
<p class=inset>Added this list.</p>

<p class=inset>Improved answer to <a href="newbie.html#q3">Question 2.3</a>, including
a second method for getting the local IP address, and adding some caveats
to the first method.</p>

<p class=inset>Refined answer to <a href="newbie.html#q4">Question 2.4</a>, making
the distinction between non-blocking and blocking sockets. What was
previously called non-blocking is now called "asynchronous". (This was
not incorrect, just imprecise.) Also corrected some misconceptions about
the behavior of blocking sockets.</p>
