Maybe already known stuff, but.....

Today I found this :

#include "execinfo.h"

void BT(void)
{
    void *array[50];
    size_t size;
    char **strings;
    size_t i;
    
    size = backtrace (array, 50);
    strings = backtrace_symbols (array, size);
    
    printf ("Obtained %zd stack frames.\n", size);
    
    for (i = 0; i < size; i++)
    printf ("%s\n", strings[i]);
    
    free (strings);
}

That allow to dump a backtrace (here max 50 frames) from inside a running program.
Quite useful if app is non debuggable and don't run with +relay on because
of copy protection.
