# Lick Scry Reference

Here are Lick's scry endpoints. There's only a few and they're mostly just useful for debugging. All of Lick's scries are specified by a `$care`. The `$desk` field in the `$beak` must be empty (`%$`, e.g. `/=//=`).

The only novel data type is a `$name`, which is just a `$path` representing the name of a socket.

## `%a` - Read ports <a href="#a---read-ports" id="a---read-ports"></a>

A scry with a `$care` of `%a` will return a list of all registered IPC ports.

```
.^((list name:lick) %la /=//=/ports)
~[/hood/reciept/control /slick/control]
```

***

## `%d` - Port owner <a href="#d---port-owner" id="d---port-owner"></a>

A scry with a `$care` of `%d` and the socket `$name` in the `$spur` will return the `$duct` of the IPC port owner in a `+unit`, which is null if the socket doesn't exist.

```
.^((unit duct) %ld /=//=/[port-name])
[~ [i=/gall/use/slick/0w3.IZWEn/~nec t=[i=/dill t=~[//term/1]]]]
```

***

## `%u` - Port existance <a href="#u---port-existance" id="u---port-existance"></a>

A scry with a `$care` of `%u` and the socket `+name` in the `$spur` will return a `?` which is `%.y` if the socket exists in Lick's state.

```
.^(? %lu /=//=/slick/control)
%.y
```
