Ashwin,
Thanks for your note. I read the debug stuff before posting but assumed it wasn't meant for runtime use. I guess I should be more specific. I need to retrieve a few thousand functions names per second. Under the debug section it says "The lua_getinfo function checks how the function was called or whether it is the value of a global variable to find a suitable name. If it cannot find a name, then name is set to NULL." So if I have:
function Foo()
-- some code here
end
And then...
function Fooey()
SetSomeValueInTheCHost(Foo)
end
And my C host has...
int SetSomeValueInTheCHost(lua_State *luaStatePtr)
{
// the first value on the lua stack is a function, how can I get the name fast here?
// candidates include getfuncname or getobjname?
}
With the decalration as per above, would getfuncname or getobjname retrieve anything useful? Is there a better/faster way?
Thanks,
Brett
