   7 # LTTng-UST libc wrapper
   8
   9 `liblttng-ust-libc` is used for instrumenting some calls to libc in a program,
  10 without need for recompiling it.
  11
  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()`.
