About storage

[LordAioria]

I have updated to create a new custom storage:

int storage_storageopen(struct map_session_data *sd)
{
struct special_storage_data *spStorage;

nullpo_ret(sd);
ShowError("storage_storageopen %d\n",sd->state.storage_flag);
if(sd->state.storage_flag)
{
 return 1; //Already open?
}

if( !pc_can_give_items(sd) )
  { //check is this GM level is allowed to put items to storage
 clif_displaymessage(sd->fd, msg_txt(246));
 return 1;
}
// Test IF is a special storage.
if (sd->specialStorage != 0)
{
 spStorage = special2SpecialStorage(sd->specialStorage, sd->typeStorage);
 spStorage->storage_status = 1;
 sd->state.storage_flag = 1;
 chrif_save(sd, 0);
 storage_sortitem(spStorage->items, ARRAYLENGTH(spStorage->items));
 clif_storagelist(sd, spStorage->items, ARRAYLENGTH(spStorage->items));
 clif_updatestorageamount(sd, spStorage->storage_amount, MAX_STORAGE); 
}
else
{
 sd->state.storage_flag = 1;
 storage_sortitem(sd->status.storage.items, ARRAYLENGTH(sd->status.storage.items));
 clif_storagelist(sd, sd->status.storage.items, ARRAYLENGTH(sd->status.storage.items));
 clif_updatestorageamount(sd, sd->status.storage.storage_amount, MAX_STORAGE);
}
return 0;
}

The thing is that i can see that the storage is opened and it shows the items that i have in spStorage->items ... but there are some problems :

* I cannot close the storage

* If user 1 opens this special storage , and another char tries to open this storage at the same time .... is allowed ... i don't understand why ....

My objective is to have a custom storage in another table ... for example custom_storage ....

Could you help me please?
