Query whether an Aio or list of Aios 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.
.unresolved(x)
Logical TRUE if ‘aio’ is an unresolved Aio or else FALSE, or if ‘aio’ is a list, the integer number of unresolved Aios in the list.
an Aio or list of Aios (objects of class ‘sendAio’, ‘recvAio’ or ‘ncurlAio’).
.unresolved()
is not intended to be used for ‘recvAio’
returned by a signalling function, in which case unresolved
must be used in all cases.
