You have the (relative) file name/path; you passed it to
luaL_loadfile. Parsing the error message is your best option (afaik):

if (luaL_loadfile(L, "filepath") == LUA_ERRSYNTAX)
{
  lua_getfield(L, -1, "match");
  lua_pushvalue(L, -2);
  lua_pushliteral(L, ":(%d+):");
  lua_call(L, 2, 1);
  // Do something with the line number...
}

Cheers,
