trcnm Command

Purpose

Generates a kernel name list.

Syntax

trcnm [ -a [ FileName ] ] | [ FileName ] | -KSymbol1 ...

Description

The trcnm command generates a kernel name list used by the trcrpt command. A kernel name list is composed of a symbol table and a loader symbol table of an object file. The trcrpt command uses the kernel name list file to interpret addresses when formatting a report from a trace log file. For more information, see the trcrpt -n command.

If the FileName parameter is not specified, the default FileName is /unix.

Flags

Item	Description
-a	Writes all loader symbols to standard output. The default is to write loader symbols only for system calls.
-KSymbol...	Obtains the value of all command line symbols through the knlist command system call.

Examples

To obtain the value of the symbols in /unix, enter:
```
trcnm -K environ errno
```
This command sequence displays the following:
```
environ 2FF7FFF8
errno 2FF7FFFC
```

To print a symbol table for system calls, enter:

trcnm

A list similar to the following is generated:

pin_obj_start    00000000
header_offset    00000008
ram_disk_start   0000000C
