7 # LTTng-UST libc wrapper
9 `liblttng-ust-libc` is used for instrumenting some calls to libc in a program,
10 without need for recompiling it.
12 This library defines a `malloc()` function that is instrumented with a
13 tracepoint. It also calls the libc `malloc()` afterwards. When loaded with
14 LD\_PRELOAD, it replaces the libc `malloc()` function, in effect instrumenting
15 all calls to `malloc()`. The same is performed for `free()`.
17 See the "run" script for a usage example.
