NAME

luaL_newmetatable — creates a new table to be used as a metatable for userdata, function indicator [-0, +1, m]

SYNOPSIS

#include <lauxlib.h>

int
luaL_newmetatable(lua_State *L, const char *tname);

DESCRIPTION

If the registry already has the key tname, returns 0. Otherwise, creates a new table to be used as a metatable for userdata, adds it to the registry with key tname, and returns 1.

In both cases pushes onto the stack the final value associated with tname in the registry.
