Parameters
ConsoleId An input double-word integer variable. The ConsoleId parameter is
the remote host console identification. Obtain the value for this
parameter by calling NRJEConsole before you call this intrinsic.
Result An eight-element integer output array. The Reply array contains
error codes which occurred during execution of this intrinsic.
If no error took place, and a message is waiting, the first element
of the Reply array is set to zero. If the first element of Reply=97,
no message was received.
The structure of the Reply array is the same as the Result array
described in "Parameters Common to NRJE Intrinsics," in the
introduction to chapter 5.
Always test the first word of Reply to determine whether any
outstanding host remote console messages are waiting to be received.
The first word of Reply is set to zero if no error took place.
Description
Call NRJEConsCheck to indicate whether any outstanding host remote
console messages are waiting to be received. Obtain the ConsoleId value
by calling NRJEConsole first. Test Reply to determine if messages are
waiting to be received.
NOTE The NRJEConsCheck intrinsic uses Reply as a message- waiting
indicator. Other NRJE intrinsics use the last formal parameter for
error indication only.
While you own the host remote console, you receive all recent host remote
console messages directed to your workstation. These messages may be in
response to commands other than those you issued.
NRJEConsCheck is used with the following intrinsics:
* NRJERcvMsg: to read one recent remote host console message.
* NRJERelease: to relinquish ownership of the remote host console.
