lttng-ust-dl(3)
===============
:object-type: library


NAME
----
lttng-ust-dl - Dynamic linker tracing (LTTng-UST helper)


SYNOPSIS
--------
Launch your application by preloading `liblttng-ust-dl.so`:

[role="term"]
[verse]
*LD_PRELOAD=liblttng-ust-dl.so* my-app


DESCRIPTION
-----------
When the `liblttng-ust-dl.so` library is preloaded before a given
application starts, it causes all calls to man:dlopen(3) and
man:dlclose(3) in said application to be traced with LTTng-UST (see
man:lttng-ust(3)).

See man:lttng(1) to learn more about how to control LTTng tracing
sessions.

The following LTTng-UST events are available when using this library:

`lttng_ust_dl:dlopen`::
    Emitted when man:dlopen(3) is called.
