libmallocwrap/README

   1 libmallocwrap is used for instrumenting calls to malloc(3) in a program, without
   2 need for recompiling it.

   4 libmallocwrap defines a malloc() function that is instrumented with a marker. It
   5 also calls the libc malloc afterwards. When loaded with LD_PRELOAD, it replaces
   6 the libc malloc() function, in effect instrumenting all calls to malloc().
