NAME
whocalls - report on the calls to a specific procedure
SYNOPSIS
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
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.
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
The following 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
