library with "-llttng-ust".
- Include the tracepoint provider header into all C files using
the provider.
- - Example:
- - tests/hello/ hello.c tp.c ust_tests_hello.h Makefile.example.*
+ - Examples:
+ - doc/examples/easy-ust/ sample.c sample_component_provider.h
+ tp.c Makefile
+ - doc/examples/hello-static-lib/ hello.c tp.c ust_test_hello.h
+ Makefile
2) Compile the Tracepoint Provider separately from the application,
using dynamic linking:
needed. Another way is to dlopen the tracepoint probe when needed
by the application.
- Example:
- - tests/demo/ demo.c tp*.c ust_tests_demo*.h demo-trace
+ - doc/examples/demo demo.c tp*.c ust_tests_demo*.h demo-trace Makefile
- - Enable instrumentation and control tracing with the "lttng" command
- from lttng-tools. See lttng-tools doc/quickstart.txt.
- Note about dlclose() usage: it is not safe to use dlclose on a
provider shared object that is being actively used for tracing due
to a lack of reference counting from lttng-ust to the used shared
object.
+ - Enable instrumentation and control tracing with the "lttng" command
+ from lttng-tools. See lttng-tools doc/quickstart.txt.
+ - Note for C++ support: although an application instrumented with
+ tracepoints can be compiled with g++, tracepoint probes should be
+ compiled with gcc (only tested with gcc so far).
