c - Using ptrace to generate a stack dump -

-

i compiling c++ on *nix , generate stack dump a) @ arbitrary point in program, b) during signal, particularly during sigsegv.

google tells me ptrace tool job, can't find comprehensible examples of walking stack. getting return address, yeah, next return address? , extracting symbolic name of function @ point? dwarf?

many if can tell me go here.

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
