NAME
       pstack - print a stack trace for each LWP in each process and core file

SYNOPSIS

DESCRIPTION
       prints  a stack trace (hex+symbolic) for each LWP (Lightweight Process)
       in each process and core file.

       Given the pid of a running process or the full path  of	a  core	 file,
       prints  the  stack trace for each LWP thread in the process.  To obtain
       symbol  information,  searches  load  modules  (executable  and	shared
       libraries) in the current directory, and You can specify the executable
       path with the pid/corepath, separated by a colon character.  If	cannot
       find a load module, symbol information for frames in that module is not
       displayed.

       works by attaching to the running process and  reading  its  registers,
       memory, and stack.  Mismatch between executable and corefile may result
       in unpredictable behavior.

   Options
       supports the following option:

	      Prints the usage menu.

	      Prints the tool version information.

   Operand
       supports the following operand:
	      pid identifies a running process, with an optional execpath, the
	      full executable path.

		     corepath  is  the	full  path  name of the specified exe‐
		     cutable.

RETURN VALUES
       returns the following values:

	      Successful completion.
	      Failure.
		      An error has occurred.
