lua_tointegerx

lua_tointegerx[-0, +0, –]

lua_Integer lua_tointegerx (lua_State *L, int index, int *isnum);

Converts the Lua value at the given index to the signed integral type lua_Integer. The Lua value must be an integer, or a number or string convertible to an integer (see §3.4.3); otherwise, lua_tointegerx returns 0.

If isnum is not NULL, its referent is assigned a boolean value that indicates whether the operation succeeded.
