MLEAK(1)
NAME
mleak - locates memory leaks in an mpatrol log file
SYNOPSIS
mleak [options] [file]
DESCRIPTION
The mleak command is used to display all unfreed memory allocations
from a log file produced by the mpatrol library. This should be used
if the mpatrol library could not finish writing the log file due to
abnormal program termination (which would prevent the SHOWUNFREED
option from working), but note that some of the unfreed allocations
might have been freed if the program had terminated successfully.
The mleak command scans through an mpatrol log file looking for lines
beginning with ALLOC: and FREE: but ignores lines beginning with REALLOC:, so only the LOGALLOCS and LOGFREES options are necessary when
running a program linked with the mpatrol library. Note that as a
result of this, no attempt is made to account for resizing of memory
allocations and so the total amount of memory used by the resulting
unfreed allocations may not be entirely accurate.
This command will also read the unfreed allocations table produced by
the SHOWUNFREED option in the log file if one is present. The entries
in the table will be compared with the currently allocated entries and
will be added if not already present.
The file argument must be a valid mpatrol log filename but if file is
omitted then mleak will use mpatrol.log as the name of the log file to
use. The mleak command makes two passes over the log file so the file
must be randomly-accessable. If file is given as - then the standard
input file stream will be used as the log file.
OPTIONS
- --help [-h]
- Displays a quick-reference option summary.
- --ignore [-i]
- Specifies that the list of unfreed allocations in the log file should be ignored.
- --max-stack depth [-n]
- Specifies the maximum stack depth to display for each unfreed memory allocation. If depth is 0 then the call stack depth will be unlimited in size. The default call stack depth is 0.
- --version [-V]
- Displays the version number of the mleak command.
