<a name="index-source-annotation-3149"></a>The following annotation is used instead of displaying source code:
|
||
|
|
|
||
|
|
<pre class="smallexample"> ^Z^Zsource <var>filename</var>:<var>line</var>:<var>character</var>:<var>middle</var>:<var>addr</var>
|
||
|
|
</pre>
|
||
|
|
<p>where <var>filename</var> is an absolute file name indicating which source
|
||
|
|
file, <var>line</var> is the line number within that file (where 1 is the
|
||
|
|
first line in the file), <var>character</var> is the character position
|
||
|
|
within the file (where 0 is the first character in the file) (for most
|
||
|
|
debug formats this will necessarily point to the beginning of a line),
|
||
|
|
<var>middle</var> is ‘<samp><span class="samp">middle</span></samp>’ if <var>addr</var> is in the middle of the
|
||
|
|
line, or ‘<samp><span class="samp">beg</span></samp>’ if <var>addr</var> is at the beginning of the line, and
|
||
|
|
<var>addr</var> is the address in the target program associated with the
|
||
|
|
source which is being displayed. The <var>addr</var> is in the form ‘<samp><span class="samp">0x</span></samp>’
|
||
|
|
followed by one or more lowercase hex digits (note that this does not
|
||
|
|
depend on the language).
