NAME

luaL_callmeta — calls a metamethod, function indicator [-0, + (0|1), e]

SYNOPSIS

#include <lauxlib.h>

int
luaL_callmeta(lua_State *L, int obj, const char *e);

DESCRIPTION

luaL_callmeta() calls a metamethod.

RETURN VALUES

If the object at index obj has a metatable and this metatable has a field e, this function calls this field and passes the object as its only argument. In this case this function returns 1 and pushes onto the stack the value returned by the call. If there is no metatable or no metamethod, this function returns 0 (without pushing any value on the stack).
