This should be used if thempatrol library could not finish writing the log file due to abnormal programtermination (which would prevent the <B>SHOWUNFREED</B> option from working),but note that some of the unfreed allocations might have been freed if theprogram had terminated successfully.<P>The <B>mleak</B> command scans through an mpatrol log file looking for linesbeginning with <I>ALLOC:</I> and <I>FREE:</I> but ignores lines beginning with<I>REALLOC:</I>, so only the <B>LOGALLOCS</B> and <B>LOGFREES</B> options arenecessary when running a program linked with the mpatrol library. Note thatas a result of this, no attempt is made to account for resizing of memoryallocations and so the total amount of memory used by the resulting unfreedallocations may not be entirely accurate.<P>This command will also read the unfreed allocations table produced by the<B>SHOWUNFREED</B> option in the log file if one is present. The entries in thetable will be compared with the currently allocated entries and will be addedif not already present.<P>The <I>file</I> argument must be a valid mpatrol log filename but if <I>file</I>is omitted then <B>mleak</B> will use <I>mpatrol.log</I> as the name of the logfile to use. The <B>mleak</B> command makes two passes over the log file sothe file must be randomly-accessable. If <I>file</I> is given as <I>-</I> thenthe standard input file stream will be used as the log file.<A NAME="lbAE"> </A><H2>OPTIONS</H2><DL COMPACT><DT><B>--help</B> [<B>-h</B>]<DD>Displays a quick-reference option summary.<DT><B>--ignore</B> [<B>-i</B>]<DD>Specifies that the list of unfreed allocations in the log file should beignored.<DT><B>--max-stack</B> <I>depth</I> [<B>-n</B>]<DD>Specifies the maximum stack depth to display for each unfreed memory allocation.If <I>depth</I> is <I>0</I> then the call stack depth will be unlimited in size.The default call stack depth is <I>0</I>.<DT><B>--version</B> [<B>-V</B>]<DD>Displays the version number of the <B>mleak</B> command.</DL><A NAME="lbAF"> </A><H2>SEE ALSO</H2><B><A HREF="http://localhost/cgi-bin/man/man2html?1+mpatrol">mpatrol</A></B>(1), <B><A HREF="http://localhost/cgi-bin/man/man2html?1+mprof">mprof</A></B>(1), <B><A HREF="http://localhost/cgi-bin/man/man2html?1+mptrace">mptrace</A></B>(1), <B><A HREF="http://localhost/cgi-bin/man/man2html?1+mpsym">mpsym</A></B>(1),<B><A HREF="http://localhost/cgi-bin/man/man2html?1+mpedit">mpedit</A></B>(1), <B><A HREF="http://localhost/cgi-bin/man/man2html?1+hexwords">hexwords</A></B>(1), <B><A HREF="http://localhost/cgi-bin/man/man2html?3+libmpatrol">libmpatrol</A></B>(3), <B><A HREF="http://localhost/cgi-bin/man/man2html?3+libmpalloc">libmpalloc</A></B>(3).<P>The mpatrol manual and reference card.<P><A HREF="http://www.cbmamiga.demon.co.uk/mpatrol/">http://www.cbmamiga.demon.co.uk/mpatrol/</A><A NAME="lbAG"> </A><H2>AUTHOR</H2>Graeme S.
