Technical Utility: Query if an Aio is Unresolved

Description

Query whether an Aio remains unresolved. This is an experimental technical utility version of unresolved not intended for ordinary use. Provides a method of querying the busy status of an Aio without altering its state in any way i.e. not attempting to retrieve the result or message.

Usage

.unresolved(aio)

Arguments

aio

an Aio (object of class 'sendAio' or 'recvAio').

Details

.unresolved() is not intended to be used for 'recvAio' returned by a signalling function, in which case unresolved must be used in all cases.

Value

Logical TRUE if 'aio' is an unresolved Aio, or FALSE otherwise.
