# SecHostRemoveGuest

Removes a guest from a host.

```
OSStatus SecHostRemoveGuest(SecGuestRef host, SecGuestRef guest, SecCSFlags flags);
```

## Parameters

`host`

The guest code object of the host of the guest. You cannot specify a host of a host here except in the case of a dedicated host. For a dedicated host, the dedicated host is automatically substituted for its guest. See [`kSecCSDedicatedHost`](/documentation/Security/kSecCSDedicatedHost) for a discussion of dedicated hosts.

`guest`

The guest code object for the guest whose guest relationship you wish to terminate.

`flags`

Optional flags; see [`SecCSFlags`](/documentation/Security/SecCSFlags) for possible values. Pass [`kSecCSDefaultFlags`](/documentation/Security/SecCSFlags/kSecCSDefaultFlags) for standard behavior.

## Return Value

A result code. See [Code Signing Services Result Codes](/documentation/Security/code-signing-services-result-codes).

## Discussion

This function removes all memory of the guest-host relationship from the Code Signing Services hosting system. You cannot remove a dedicated guest. The specified guest must have been created using the [`SecHostCreateGuest`](/documentation/Security/SecHostCreateGuest) function. If you remove a guest that is also a host, all of the guest’s guests are removed, recursively, as well, even if one or more of those guests are dedicated hosts.

[`SecHostCreateGuest`](/documentation/Security/SecHostCreateGuest)

Creates a new guest and describes its initial properties.
