lua_type(lua_State *L, int index);

DESCRIPTION

lua_type() returns the type of the value in the given acceptable index, or LUA_TNONE for a non-valid index (that is, an index to an "empty" stack position). The types returned by lua_type are coded by the following constants defined in lua.h: LUA_TNIL, LUA_TNUMBER, LUA_TBOOLEAN, LUA_TSTRING, LUA_TTABLE, LUA_TFUNCTION, LUA_TUSERDATA, LUA_TTHREAD, and LUA_TLIGHTUSERDATA.
