Evaluates forms in the scope of a temporary autorelease pool.
with-autorelease-pool (option*) form* => values
There are currently no options.
The values returned by the last form.
with-autorelease-pool creates a new autorelease pool and evaluates each form in sequence. The pool is released at the end, even if a non-local exit is performed by the forms. An autorelease pool is provided automatically for the main thread when running CAPI with Cocoa, but other threads need to allocate one if they call Objective-C methods that use autorelease.
"description" method returns an autoreleased
NSString, so to make this function safe for use anywhere, the
with-autorelease-pool macro is used:
(defun object-description (object)
(invoke-into 'string object "description")))
