Re: Something like "ping" for windows messages.

The third-party socket libraries I know of come with source (in a couple cases it's an
extra-price feature). And they run on a large number of platforms; I forget which ones
run on AS/400, but I know one of them does.

Recently a colleague was creating a mutex with CMutex. He wanted to do

mutex). Thin layers that simply remove functionality don't see that
great to me.

How did we get from sockets to mutexes? Most experienced MFC programmers know that the
whole set of wrapper classes for synchronization primitives just suck, and should be
avoided. And what does a defective design of synchronization primitives relate to the
socket design? They almost certainly were done by different people (and the person doing
the synchronization classes seems to have been somewhat clueless).

I thought it was another example of a very simple wrapper class that
adds very little but (presumably) hides features documented in the
Win32 API. In those cases, I can't see why using the Win32 API is a
bad idea.

When I teach networking, I tell my students that if they want portbility, the correct
solution is to buy a third-party socket libary that is designed to be portable.

I think there were some of those on that faq website I put in my last
reply. I didn't see much advantage in that though as having 3rd party
code in your product is always a nightmare. Usually you don't get the
source so if there's a problem you're in trouble. Some of our code
could run on about 10 different versions of UNIX, Windows, AS/400 and
MPE systems. Getting hold of the correct binary (64 bit/32 bit, Linux
kernel versions etc.) or porting a 3rd party library was something we
often had to do (ISAM libraries for example) and was often the cause a
hold up beyond our control when getting a product out.

Sure you have to port your own code but that's going to be much smaller
and simpler then a generic library that has many more features than you
need.

Cheers.

Peter.
