NAME

lua_topointer — converts the value to a generic C pointer, function indicator [-0, +0, -]

SYNOPSIS

#include <lua.h>

const void *
lua_topointer(lua_State *L, int index);

DESCRIPTION

lua_topointer() converts the value at the given acceptable index to a generic C pointer (void*). The value can be a userdata, a table, a thread, or a function; otherwise, lua_topointer returns NULL. Different objects will give different pointers. There is no way to convert the pointer back to its original value.

Typically this function is used only for debug information.
