whocalls(1) User Commands whocalls(1)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 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
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

elfdump(1) User Commands elfdump(1)NAME
elfdump - dumps selected parts of an object file
SYNOPSIS
elfdump [-cCdegGhHiklmnprsuvy] [-N name] [-w file] filename...
DESCRIPTION
The elfdump utility symbolically dumps selected parts of the specified object file(s). The options allow specific portions of the file to
be displayed.
The elfdump utility is similar in function to the dump(1) utility. The dump utility offers an older and less user-friendly interface than
elfdump, although dump might be more appropriate for certain uses such as in shell scripts.
Archive files, produced by ar(1), can also be inspected with elfdump. In this case, each object within the archive is processed using the
options supplied.
For a complete description of the displayed information, refer to the Linker and Libraries Guide.
OPTIONS
The following options are supported:
-c Dumps section header information.
-C Demangles C++ symbol names.
-d Dumps the contents of the .dynamic section.
-e Dumps the ELF header.
-g Dumps the contents of the .group section.
-G Dumps the contents of the .got section.
-h Dumps the contents of the .hash section.
-H Dumps the contents of the .SUNW_cap hardware and software capabilities section.
-i Dumps the contents of the .interp section.
-k Calculates the ELF checksum. See gelf_checksum(3ELF).
-l Displays long section names without truncation.
-m Dumps the contents of the .SUNW_move section.
-n Dumps the contents of the .note section.
-N name Qualifies an option with a specific name. For example, in a file that contains more than one symbol table, the .dynsym ta-
ble can be displayed using:
example% elfdump -s -N .dynsym filename
-p Dumps the program headers.
-r Dumps the contents of the .rel[a] relocation sections.
-s Dumps the contents of the .dynsym and .symtab symbol table sections. For archives, the archive symbol table is also dumped.
Individual sections can be specified with the -N option. An archive symbol table can be specified using the special section
name -N ARSYM.
In the case of core files, the shndx field will have the value "unknown" since the field does not contain the valid values.
In addition to the standard symbol table information, the version definition index of the symbol is also provided under the
ver heading.
-u Dumps the contents of a frame unwind.
-v Dumps the contents of the .SUNW_version version sections.
-w file Writes the contents of a section that is specified with the -N option, to the named file. For example, extracting the .text
section of a file can be carried out with:
example% elfdump -w text.out -N .text filename
-y Dumps the contents of the .SUNW_syminfo section.
OPERANDS
The following operand is supported:
filename The name of the specified object file.
FILES
liblddbg.so linker debugging library
