Topic: SIGPOLL XSR option
Relevant Sections: XBD signal.h------------------------------------------------------------------------
7 Defect Report concerning (number and title of International Standard or DIS final text, if applicable):
The Base Definitions Volume of IEEE Std 1003.1-2001
------------------------------------------------------------------------
8 Qualifier (e.g. error, omission, clarification required):
1. Error
------------------------------------------------------------------------
9 References in document (e.g. page, clause, figure, and/or table numbers):
XBD page 305 line 10856 <signal.h>
XBDbug2.txt Enhancement Request Number 23
------------------------------------------------------------------------
10 Nature of defect (complete, concise explanation of the perceived problem):
STREAMS support is optional and interfaces directly related to streams are shaded [XSR] throughout the standard. For example, stropts.h, isastream, getmsg, getpmsg, ioctl, putmsg, putpmsg, fattach, fdetach are all shaded [XSR].
SIGPOLL is defined in signal.h
Aside from signal.h, SIGPOLL is only ever discussed in XSR related text.
Since the SIGPOLL signal is only used by the above STREAMS interfaces, we think it should be shaded [XSR] in signal.h. Currently SIGPOLL is [XSI].
------------------------------------------------------------------------
11 Solution proposed by the submitter (optional):
SIGPOLL references in signal.h should be shaded [XSR].
------------------------------------------------------------------------
Interpretation response ------------------------
The standards states the requirements for SIGPOLL to be supported as part of the XSI option, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor.
Rationale: ----------- The semantics of SIGPOLL are only specified with functionality in the XSR option.
