Name
luaL_getconstant -- get constant value (V9.0)
Synopsis
int ok = luaL_getconstant(lua_State *L, const char *name,
             lua_Number *nval, char **sval);
Function
This is not an official Lua API but a Hollywood extension. luaL_getconstant() returns the value of the constant specified by name. Note that the string passed in name must not contain the #-prefix typically used by Hollywood constants. It must only contain the constant's actual name.

If the constant is a numeric one, luaL_getconstant() will write its value to the nval pointer. If it is a string constant, its value will be written to sval instead.
