- doc
The documentation.
- - hello
- An example application that uses the userspace tracer.
+ - tests
+ Various test programs
- libustinstr-malloc
An example library that can be LD_PRELOAD'ed to instrument calls to malloc()
- libustfork
A library that is LD_PRELOAD'ed, and that hijacks calls to several system
- calls in order to trace across these calls.
+ calls in order to trace across these calls. It _has_ to be LD_PRELOAD'ed
+ in order to hijack calls. In contrast, libust may be linked at build time.
+
+ - 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.
