|

|
|
<P>On
|
||
|
|
DOS/Windows systems, the home directory is the one pointed to by the
|
||
|

<CODE>HOME</CODE> environment variable.

|
||
|
|
<P>
|
||
|
|
Note that embedded programs (the so-called "free-standing"
|
||
|
|
environment) are not required to have a <CODE>main</CODE> function as the
|
||
|
|
entry point. They could even have multiple entry points.
|
||
|
|
<H3><A NAME="FOOT4" HREF="gdb_8.html#DOCF4">(4)</A></H3>
|
||
|
|
<P>
|
||
|
|
The only restriction is that your editor (say <CODE>ex</CODE>), recognizes the
|
||
|
|
following command-line syntax:
|
||
|
|
<TABLE><tr><td> </td><td class=smallexample><FONT SIZE=-1><pre>ex +<VAR>number</VAR> file
|
||
|
|
</FONT></pre></td></tr></table>The optional numeric value +<VAR>number</VAR> specifies the number of the line in
|
||
|
|
the file where to start editing.
|
||
|
|
<H3><A NAME="FOOT5" HREF="gdb_9.html#DOCF5">(5)</A></H3>
|
||
|
|
<P><SAMP>`b'</SAMP> cannot be used because these format letters are also
|
||
|
|
used with the <CODE>x</CODE> command, where <SAMP>`b'</SAMP> stands for "byte";
|
||
|
|
see <A HREF="gdb_9.html#SEC64">Examining Memory</A>.
|
||
|
|
<H3><A NAME="FOOT6" HREF="gdb_9.html#DOCF6">(6)</A></H3>
|
||
|
|
<P>This is a way of removing
|
||
|
|
one word from the stack, on machines where stacks grow downward in
|
||
|
|
memory (most machines, nowadays). This assumes that the innermost
|
||
|
|
stack frame is selected; setting <CODE>$sp</CODE> is not allowed when other
|
||
|
|
stack frames are selected. To pop entire frames off the stack,
|
||
|
|
regardless of machine architecture, use <CODE>return</CODE>;
|
||
|
|
see <A HREF="gdb_15.html#SEC151">Returning from a Function</A>.
|
||
|
|
<H3><A NAME="FOOT7" HREF="gdb_18.html#DOCF7">(7)</A></H3>
|
||
|
|
<P>If you choose a port number that
|
||
|
|
conflicts with another service, <CODE>gdbserver</CODE> prints an error message
|
||
|
|
and exits.
|
||
|
|
<H3><A NAME="FOOT8" HREF="gdb_30.html#DOCF8">(8)</A></H3>
|
||
|
|
<P>In
|
||
|
|
<TT>`gdb-6.8/gdb/refcard.ps'</TT> of the version 6.8
|
||
|
|
release.
|

|

|
|
<P>The <SAMP>`qP'</SAMP> and <SAMP>`qL'</SAMP>
|
||
|
|
packets predate these conventions, and have arguments without any terminator
|
||
|
|
for the packet name; we suspect they are in widespread use in places that
|
||
|
|
are difficult to upgrade. The <SAMP>`qC'</SAMP> packet has no arguments, but some
|
||
|
|
existing stubs (e.g. RedBoot) are known to not check for the end of the
|
||
|
|
packet.
