Ltrace is a software that monitors library calls during the execution of dynamically-linked programs.
The best part? Ltrace doesn't require the program to be traced to be recompiled, so you can use it on binaries for which you don't have the source code. This feature makes it an ideal tool for sysadmins who need to track the execution of processes.
If you want to keep up with the latest features, you'll be pleased to know that the latest release boasts an array of improvements. These include a pristine source distribution, a new Standards-Version (3.6.1), and a resolved "--indent" option (closes: Bug#265185). With all these improvements, Ltrace is definitely worth checking out!
