Hi All,
Is there a generic linked list implementation in Solaris 10 U7 along with
usage examples in the kernel ala linux? I see that even the e1000g driver seems to
use it's own linked list implementation.,just wanted to know is there any particular
reason for this? I see a <sys/list.h> and a list.c but now many users of this ?
Pls correct me if i am wrong and /or point me to it's usage /semantics?
list.c and list.h are relatively recent additions. Boomer (the audio
subsystem) uses them pretty heavily. Look in OpenSolaris in
usr/src/uts/common/io/audio/impl/*.c
Garrett - they've been there since Solaris 9 update 5. 2003 isn't
on my "recent" radar any more :-P
I figured they were introduced in S10... to me 2003 is still kind of
recent, since most of the other DDI interfaces date back to Solaris 8 or
earlier. :-)
Somnath - I strongly encourage you to use <sys/list.h> for
your code. The best way to get examples of its usage is to
use OpenGrok and see what pops up:
Yep.
http://src.opensolaris.org/source/search?q=sys%2Flist.h&defs=&refs=&path=&hist=&project=%2Fonnv
Btw, I think these interfaces should become an official part of the
DDI. I'd be happy to sponsor a fast track to make them so, if someone
else wanted to write up the initial case materials.
