Comment on Current state of SCTP by Bruce Cran

Bruce Cran — Wed, 30 Jun 2010 19:04:56 +0000

The version of sctpDrv available via the co-conv site appears to have been unmaintained since the end of 2008. I took the code that was made available via sctp.jp and have been fixing bugs and making improvements such as adding 64-bit support and fixing installation issues. The new SctpDrv site is at http://www.bluestop.org/SctpDrv/ .

Comment on How to use hash_map by thomas

oops, it butchered my comment because it had less than and greater than signs.. basically you need to pass a fourth thing to the hash_map template, which is the same as the third argument

typedef hash_map > HashObject;

should be:

typedef hash_map, HashConfiguration > HashObject;

(or at least that’s what I found when I tried this!)

Comment on Detecting TCP connection problems by Dave

Okay, this is awesome. I had no idea it existed. I’ve never had a need to prevent disconnection due to inactivity, but as you know, I am always on the lookout for more robust ways of detecting when my peer has died without properly closing its TCP connection.

Comment on Non blocking singly linked list by Alex

ChasM, thank you for your useful comment.

MSDN indeed says:

All list items must be aligned on a MEMORY_ALLOCATION_ALIGNMENT boundary; otherwise, this function will behave unpredictably.

Instead of proper allocation (which will cause editing this post) I may add some special requirements for the logging API.
Considering that on Win32 MEMORY_ALLOCATION_ALIGNMENT is 8 that makes my example suitable only for strings with length equal to 3, 11, 19,.. etc :)

Comments on WriteLogMessage:
I think the way you’ve tacked storage for the strText pointer as well as the string itself is pretty clever. I wouldn’t have thought of that.

And although it’s clearer to use new and delete like you did, the SList Interlocked functions require each allocated block to be aligned on a dword boundary, which new doesn’t do. You need to use _aligned_malloc and _aligned_free instead. The requirement for alignment is imposed by the CPU. This is a gotcha that would be very hard to debug….
