Please add <sys/poll.h>

[mjw]

This may be a bit controversial, but I'll give it a go anyway...

Most documentation for poll() states that programs using poll() should #include <poll.h>. However, this rule seems to be more honoured in the breech than the observance, with a lot of 3rd party code #including <sys/poll.h>. Haiku does not have <sys/poll.h>, so 3rd party code that #includes <sys/poll.h> needs to be modified to compile.

Posix OSs that I have seen (Linux, Solaris and NetBSD) have the main poll() header in <sys/poll.h>. <poll.h> either #includes, or is a symbolic link to, <sys/poll.h>.

I have attached a patch that makes Haiku emulate Linux/Solaris semantics: <poll.h> #includes <sys/poll.h>. This patch should not break existing Haiku/BeOS software, and will allow 3rd party apps to be ported with less modifications.

Any chance of it being applied?

I'd like to second this. Also python assumes it is in sys/poll.h.

poll.h is a POSIX header, while sys/poll.h is not. I would always prefer to fix broken software which is not POSIX conformant for no reason. Anyway, I've added a sys/poll.h header in hrev24864 that includes the POSIX poll.h header now. If that isn't okay for you, please tell.

BTW. It's a duplicate of bug 1125 marked as invalid...

Thanks Axel. Sounds like a reasonable compromise.

Considering this is not standard POSIX, I agree with Axel that the tool needs to be fixed. I will try to work it in.
