Re https://austingroupbugs.net/view.php?id=1466#c5325 A drawback of both of
those solutions is that neither has a
satisfactory retrofit for the "s" in ptsname().
The mailing list discussion in Aug 2020 included suggestions of using
"primary" for one side but without finding a good enough word for the other
side ("ancilliary" came close). It has now occurred to me that "secondary"
could be used if these words are used to indicate not the role that the
devices have but the order in which they are opened. The primary device is
opened first, and then the name of the secondary device is obtained from
ptsname() and is opened second.
I think this could be a good solution if we include an explanation of the
reason behind the naming somewhere.

[Issue 8 drafts 0001448]: Misleading text in description of poll()
A NOTE has been added to this issue. == https://austingroupbugs.net/view.php?id=1448 == Reported By:kre Assigned To: == Project:Issue 8 drafts Issue ID: 1448 Category: System Interfaces Type: Error Severity: Objection Priority: normal Status: New Name: Robert Elz Organization: User Reference: Section:XSH 3/poll() Page Number:1399-1400 Line Number:46800-1. 46807-46813, 46820, 46824, 46867 Final Accepted Text: == Date Submitted: 2021-02-02 22:12 UTC Last Modified: 2021-06-18 14:08 UTC == Summary:Misleading text in description of poll() == -- (0005386) geoffclare (manager) - 2021-06-18 14:08 https://austingroupbugs.net/view.php?id=1448#c5386 -- In the June 17th teleconference we decided that we should align the wording for poll() with what is currently used for select(), i.e. talk about descriptors being "ready for reading/writing" (with an explanation of what that means). I think the following changes are close to what we would have come up with if we hadn't run out of time. My aim in posting them here is that we should use this as the starting point on the June 24th call, but will be able to address any feedback in that call rather than waiting for a subsequent call. Page and line numbers are for draft 1.1 but the changes account for the addition of ppoll() in draft 2. In the sentence beginning on line 46801, change:on which an application can read or write datato:on which an application can make an attempt to read or write data without blocking At line 46807, change:POLLIN Data other than high-priority data may be read without blocking.to:POLLIN The file descriptor is ready for reading data other than high-priority data. In line 46808 change:POLLRDNORM Normal data may be read without blocking.to:POLLRDNORM The file descriptor is ready for reading normal data. In line 46809 change:POLLRDBAND Priority data may be read without blocking.to:POLLRDBAND The file descriptor is ready for reading priority data. In line 46810 change:POLLPRI High-priority data may be read without blocking.to:POLLPRI The file descriptor is ready for reading high-priority data. In line 46811 change:POLLOUT Normal data may be written without blocking.to:POLLOUT The file descriptor is ready for writing normal data. In line 46813 change:POLLWRBAND Priority data may be written.to:POLLWRBAND The file descriptor is ready for writing priority data. In line 46814 change:An error has occurred on the device or stream.to:An error condition is present on the file descriptor. All error conditions that arise solely from the state of the object underlying the open file description and would be diagnosed by a return of -1 from a read() or write() call on the file descriptor shall be reported as a POLLERR event. On line 46820 delete the words (and punctuation):; a stream can never be writable if a hangup has occurred On line 46824 change:is invalidto:is not an open file descriptor Before line 46826 insert a new paragraph:A file descriptor shall be considered ready for reading when a call to an input function with O_NONBLOCK clear would not block, whether or not the function would transfer data successfully. (The function might return data, an end-of-file indication, or an error other than one indicating that it is blocked, and in each of these cases the descriptor is considered ready for reading.) A file descriptor shall be considered ready for writing when a call to an output function with O_NONBLOCK clear would not block, whether or not the function would transfer data successfully. How much data could be written without blocking depends upon the object underlying the open file description and its current state. On line 46826-7 after:The significance and semantics of normal, priority, and high-priority data are file and device-specific.add:The semantics of device disconnection are device-specific. On line 46867 change APPLICATION USAGE from:Noneto:When a poll() or ppoll() call indicates a file descriptor is ready for reading, this means that if an attempt to read data had been made at the time that the status of the file descriptor was checked, it would have returned at least

Implementations shall support passing CLOCK_REALTIME and CLOCK_MONOTONIC to pthread_cond_clockwait() as the clock_id argument. When such timeouts occur...[keep final sentence from existing paragraph.] Remove paragraph starting at line 51677. Replace paragraph starting at line 51680 with: The pthread_cond_timedwait() function shall be equivalent to pthread_cond_clockwait(), except that it lacks the clock_id argument. The clock to measure abstime against shall instead come from the condition variable's clock attribute which can be set by pthread_condattr_setclock() prior to the condition variable's creation. If no clock attribute has been set, the default shall be CLOCK_REALTIME.
