+application to be traced with LTTng. In addition to loading this
+library, enabling this tracing requires the following two events to be
+enabled: "ust_baddr:push" and "ust_baddr:pop".
.SH "DESCRIPTION"
The events have the following detailed definitions:
.PP
.IP "ust_baddr:push"
-This event is used to trace dlopen calls. The base address (where the dynamic
-linker has placed the shared object) is recorded in the baddr-field. The path
-to the shared object gets recorded in the sopath-field (as string). The file
-size of the loaded object (in bytes) is recorded to the size-field and its time
-of last modification (in seconds since Epoch) is recorded in the mtime-field.
+This event is used to trace dlopen calls. The base address (where the
+dynamic linker has placed the shared object) is recorded in the "baddr"
+field. The path to the shared object gets recorded in the "sopath" field
+(as string). The file size of the loaded object (in bytes) is recorded
+to the "size" field and its time of last modification (in seconds since
+Epoch) is recorded in the "mtime" field.
.IP "ust_baddr:pop"
This event is used to trace dlclose calls. The base address of the shared
-object that got closed is recorded in the baddr-field.
+object that got closed is recorded in the "baddr" field.

.IP "ust_baddr_statedump:soinfo"
This event is used to trace a currently loaded shared object. The base address
(where the dynamic linker has placed the shared object) is recorded in the
-baddr-field. The path to the shared object gets recorded in the sopath-field
-(as string). The file size of the loaded object (in bytes) is recorded to the
-size-field and its time of last modification (in seconds since Epoch) is
-recorded in the mtime-field.

-If the event above is enabled, a series of ust_baddr_statedump:soinfo events is
-recorded at session-enable time, that represents the state of currently loaded
-shared objects (of the traced application). If this information gets combined
-with the lttng-ust-dl(3) instrumentation, all aspects of dynamic loading that
-are relevant for symbol and linenumber-lookup are traced by LTTng.
