whocalls [-l wholib] [-s] funcname executable
[arguments]...
whocalls is a simple example of a utility based on the Link-Auditing functionality of ld.so.1(1) that permits the tracking of a given function call. See the Linker and Libraries Guide for a detailed description of the Link-Auditing mechanism. The executable is run as normal with any associated arguments. Each time the procedure funcname is called, both the arguments to that procedure and a stack trace are displayed on standard output.
The following options are supported:
-l wholib
-s
