Function

CFBundlePreflightExecutable(_:_:)

Returns a Boolean value that indicates whether a given bundle is loaded or appears to be loadable.

Declaration

func CFBundlePreflightExecutable(_ bundle: CFBundle!, _ error: UnsafeMutablePointer<Unmanaged<CFError>?>!) -> Bool

Parameters

bundle

The bundle to examine.

error

Upon return, if an error occurs contains a CFError that describes the problem. Ownership follows the The Create Rule.

Return Value

true if bundle is loaded or upon inspection appears to be loadable, otherwise false.

Discussion

If this function returns true, this does not mean that the bundle is definitively loadable, since it may fail to load due to link errors or other problems not readily detectable.
