Answer: strtol reusing param

That oneliner is pretty cool, I'd recommend using the tree util.

bash-3.2$ mkdir -p this/is/some/nested/example
bash-3.2$ mkdir -p this/is/another/super/nested/example
bash-3.2$ mkdir -p this/is/yet/another/example
bash-3.2$ mkdir -p this/is/some/nested/other/example
bash-3.2$ tree this
this
`-- is
    |-- another
    |   `-- super

    |           `-- example
    |-- some
    |   `-- nested

See backtrace().

e.g.

#include <execinfo.h>
#include <stdio.h>

void bar() {
  void* callstack[128];
  int i, frames = backtrace(callstack, 128);
  char** strs = backtrace_symbols(callstack, frames);
  for (i = 0; i < frames; ++i) {
    printf("%s\n", strs[i]);
  }
  free(strs);
}

int foo() {
  bar();
  return 0;
}

int main() {
  foo();
  return
