--- name: "kmtrace" section: "1" platform: "linux" package: "kmtrace" version: "4:3.5.9-2" release: "Debian 5.0 (Lenny)" platforms: ["linux"] url: "https://new.carta.tech/kmtrace" --- # kmtrace(1) a KDE memory leak tracer ## NAME kmtrace - a KDE memory leak tracer ## SYNOPSIS **kmtrace** \[ *generic-options* \] \[ **-x, --exclude** *file* \] \[ **-e, --exe** *file* \] \[ **-t, --tree** *file* \[ **--th, --treethreshold** *value* \] \[ **--td, --treedepth** *value* \]\] \[ *trace-log* \] ## DESCRIPTION **KMtrace** is a KDE tool to assist with malloc debugging using glibc's "mtrace" functionality. Unfortunately the mtrace that is part of current (9/9/2000) glibc versions only logs the return-address of the malloc/free call. The library included with KMtrace logs a complete backtrace upon malloc/free. KMtrace will investigate the trace log specified on the command line, or *ktrace.out* if no trace log is specified. This utility is part of the KDE Software Development Kit. ## OPTIONS Below are the kmtrace-specific options. For a full summary of options, run *kmtrace --help*. - **-x, --exclude** *file* File containing symbols to exclude from output. - **-e, --exe** *file* Executable to use for looking up unknown symbols. - **-t, --tree** *file* Write a tree of the allocations to the given file. - **--th, --treethreshold** *value* When writing the allocations tree, hide subtrees allocating less than the given memory amount. - **--td, --treedepth** *value* When writing the allocations tree, hide subtrees that are deeper than the specified depth. ## SEE ALSO [**demangle**(1)](/demangle/1.md), [**kminspector**(1)](/kminspector/1.md), [**kmmatch**(1)](/kmmatch/1.md).
