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.
Value
Logical TRUE
if x
is an unresolved Aio or else FALSE
, or if x
is a list, the integer number of unresolved Aios in the list.
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.
