NAME
trace - Display the stack trace of a process
SYNOPSIS
trace address
dtrace address
DESCRIPTION
The trace macro takes the address of a process
as an argument. It displays the stack backtrace
of the given process.
The dtrace macro loops, beginning with the given process, printing trace information for each process in turn, until the p_next field is null.
Typical output looks like this:
