PACKAGE CONTENTS: This package contains the following elements. - libust The actual userspace tracing library that must be linked to the instrumented programs. - ustctl A program to control the tracing of userspace applications. It can list markers, start the tracing, stop the tracing, enable/disable markers, etc. - include The public header files that will be installed on the system. - ustd The daemon that collects trace data and writes it to the disk. - doc The documentation. - tests Various test programs - libustinstr-malloc An example library that can be LD_PRELOAD'ed to instrument calls to malloc() in any program without need to recompile it. - libustfork A library that is LD_PRELOAD'ed, and that hijacks calls to several system calls in order to trace across these calls. - libustcmd A library to control tracing in other processes. Used by ustctl. - libustcomm A static library shared between libust, ustd and libustcmd, that provides functions that allow these components to communicate together. - snprintf An asynchronous signal-safe version of snprintf. - java A simple library that uses JNI to allow tracing in java programs.
