<div class="example">
<pre class="example"> <indirect table> =
<separator>
Indirect:
(<filename>: <bytepos>)*
</pre></div>
<p>The indirect table is written to the main file in the case of split
output only. It specifies, as a decimal integer, the starting byte
position (zero-based) that the first node of each subfile would have if
the subfiles were concatenated together in order, not including the
top-level file. The first node of actual content is pointed to by the
first entry.
</p>
<p>As an example, suppose split output is generated for the GDB manual.
The top-level file <samp>gdb.info</samp> will contain something like this:
</p>
<div class="example">
<pre class="example"><separator>
Indirect:
gdb.info-1: 1878
gdb.info-2: 295733
...
</pre></div>
<p>This tells Info viewers that the first node of the manual occurs at
byte 1878 of the file <samp>gdb.info-1</samp> (which would be after that file’s
preamble.) The first node in the <samp>gdb.info-2</samp> subfile would start at
byte 295733 if <samp>gdb.info-2</samp> were appended to <samp>gdb.info-1</samp>,
including any preamble sections in both files.
</p>
<p>Unfortunately, Info-creating programs such as <code>makeinfo</code> have not
always implemented these rules perfectly, due to various bugs and
oversights. Therefore, robust Info viewers should fall back to
searching “nearby” the given position for a node, instead of
giving up immediately if the position is not exactly at a node beginning.
