ltrace is a diagnostic and debugging tool for the command line that can be used to display calls that are made to shared libraries. It uses the dynamic library hooking mechanism, which prevents it from tracing calls to statically linked libraries. ltrace also displays return values of the library calls. The output is printed to standard error output or to a selected file.
Red Hat Developer Toolset is distributed with ltrace 0.7.91. While the base version ltrace remains the same as in the previous release of Red Hat Developer Toolset, various enhancements and bug fixes have ported.
