Function

SecHostSetGuestStatus(_:_:_:_:)

Updates the status and attributes of a particular guest.

Declaration

func SecHostSetGuestStatus(_ guestRef: SecGuestRef, _ status: UInt32, _ attributes: CFDictionary?, _ flags: SecCSFlags) -> OSStatus

Parameters

guestRef

The guest code object of the code on whose behalf this thread is acting.

status

A new set of code status flags for the guest (see SecCodeStatus. The host must enforce the restrictions on changes to guest status: the valid bit can only be cleared and the hard and kill flags can only be set. Pass the previous guest status to indicate that no change is desired.

attributes

A key-value dictionary of attributes that can be used to identify this particular guest among all of the caller’s guests. If you include this dictionary, it completely replaces earlier-specified attributes. Pass NULL for this parameter if you do not want to change the attributes for this guest. Although you can specify any key-value pairs in this attributes dictionary, the keys in Guest Attribute Dictionary Keys are conventionally used for this purpose.

flags

Optional flags; see SecCSFlags for possible values. Pass kSecCSDefaultFlags for standard behavior.

Return Value

Discussion

This function must be called by a host acting in proxy mode every time the status of a guest changes so that Code Signing Services can update the information cache for that guest. The specified guest must have been created using the SecHostCreateGuest(_:_:_:_:_:_:) function.
