       pstack - print a stack trace of running processes

       pstack pid [...]

       pstack  attaches to the active processes named by the pids on the command line, and prints
       out an execution stack trace, including a hint at what the  function  arguments	are.   If
       symbols exist in the binary (usually the case unless you have run strip(1)), then symbolic
       addresses are printed as well.

       If the process is part of a thread group, then pstack will print out  a	stack  trace  for
       each of the threads in the group.

       pstack  currently  works only on Linux, only on an x86 machine running 32 bit ELF binaries
       (64 bit not supported).	Also, for symbolic information, you need to use a GNU compiler to
       generate your program, and you can't strip symbols from the binaries.  For thread informa-
       tion to be dumped, you have to use the debug-aware version of libpthread.so.   (To  check,
       run    nm(1)    on    your   pthreads   library,   and	make   sure   that   the   symbol
       "__pthread_threads_debug" is defined.)
