Query whether an Aio or Aio value remains unresolved. Unlike
call_aio, this function does not wait for completion.
unresolved(aio)an Aio (object of class 'sendAio' or 'recvAio'), or Aio value
stored in $result, $raw or $data as the case may be.
Logical TRUE if 'aio' is an unresolved Aio or Aio value, or FALSE otherwise.
Suitable for use in control flow statements such as while or
if.
Note: querying resolution may cause a previously unresolved Aio to resolve.
s1 <- socket("pair", listen = "inproc://nanonext")
aio <- send_aio(s1, "test", timeout = 100)
while (unresolved(aio)) {
# do stuff before checking resolution again
cat("unresolved\n")
s2 <- socket("pair", dial = "inproc://nanonext")
Sys.sleep(0.01)
}
#> unresolved
unresolved(aio)
#> [1] FALSE
close(s1)
close(s2)
