I'm trying to add the optional argument to the Lua function. This is what it looks like right now:
static int luaCB_get_partitionInfo( lua_State* L )
{
if (camera_info.cam_has_multipart)
{
int part;
int count = get_part_count();
int active = get_active_partition();
switch (lua_gettop(L))
{
case 0:
part = 0;
break;
case 1:
part = luaL_checknumber(L, 1);
if (part < 1 || part > count)
{
return luaL_error(L, "invalid partition number");
}
break;
default:
return luaL_error(L, "invalid argument count");
}
lua_createtable(L, 0, 4);
SET_INT_FIELD("count", count);
SET_INT_FIELD("active", active);
SET_INT_FIELD("type", get_part_type(part));
SET_INT_FIELD("size", get_part_size(part)>>10);
return 1;
}
return 0;
}
Calling get_partitionInfo() from a PTP test client crash. What am I doing wrong?
