If you want the name the function was called with, here's how Lua gets
it (and how you get those really nice argument error messages in C):
/* UNTESTED */
lua_Debug ar;
if (!lua_getstack(L, 0, &ar)) /* no stack frame? */
ar.name = "?"; /* Some default ? */
else
{
lua_getinfo(L, "n", &ar);
if (ar.name == NULL)
ar.name = "?"; /* <-- PUT DEFAULT HERE */
}
I think this is slow though? So perhaps you may want to avoid it
unless it is really necessary...
Hope that helps,
