queue.h"):
We would like some linked list macros which are (a) well known to be
sane and (b) typesafe. BSD's queue.h meets these criteria.
The files in this changeset were obtained with:
svn co -r 221843 svn://svn.freebsd.org/base/head/sys/sys/
svn co -r 221843 svn://svn.freebsd.org/base/head/share/man/man3
I posted this because I noticed (too late) that libxl_qmp.c includes
<sys/queue.h> and uses some macros that are only available in some
queue.h versions. This is not ideal for portability of course.
I think it would be good to include this massaged queue.h and use it
in libxl_qmp.c.
These headers cause build errors on *BSD due to collisions with the
native headers. Two solutions:
- Only use them on platforms where they do not exist
- Add a namespace prefix to the macros and use them consequently
