liblttng-ust-libc-wrapper/README

   1 liblttng-ust-libc is used for instrumenting some calls to libc in a
   2 program, without need for recompiling it.

   4 This library defines a malloc() function that is instrumented with a
   5 tracepoint. It also calls the libc malloc afterwards. When loaded with
   6 LD_PRELOAD, it replaces the libc malloc() function, in effect
   7 instrumenting all calls to malloc(). The same is performed for free().
