Some platforms/OSes have stack trace APIs. Check yours for stack trace
support first before delving into things like assembler/macros/etc.
Usually requires a debug build of sorts.
I used to use a massive set of macros to trace function calls. They
worked pretty well but generated massive 200MB to 300MB files per
application run. I used them when calling functions:
#define DEBUG_FUNC2(_FuncName, _Param1, _Param2) do {\
printf("%s(%s, %s)\n", #_FuncName, #_Param1, #_Param2);\
fflush(stdout);\
(_FuncName)((_Param1), (_Param2));\
} while (0)
void foo(int i, double d)
{
}
int main()
{
DEBUG_FUNC2(foo, 1, 1.0);
}
Something like that...only a lot fancier.
