NAME
       whocalls - report on the calls to a specific procedure

SYNOPSIS
       /usr/ccs/bin/whocalls [-l wholib] [-s] funcname executable [arguments...]

DESCRIPTION
       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 func-
       tion 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 dis-
       played on standard output.

OPTIONS
       The following options are supported:

       -l wholib       Specifies an alternate who.so Link-Auditing library to use.

       -s	       When available, examines and uses the .symtab symbol table for local symbols. This is a little more  expensive  than  using
		       the .dynsym symbol table, but can produce more detailed stack trace information.

EXAMPLES
       Example 1: Tracking function calls

       This example tracks the calls to printf() made by a simple helloworld program:

       example% whocalls printf helloworld
       printf(0x106e4, 0xef625310, 0xef621ba8)
	       helloworld:main+0x10
	       helloworld:_start+0x5c
       Hello World
