Hello Niels,

Sorry, it was a very long time ago... but, if I recall correctly, the IBMer who told me it was a bad choice was mostly concerned about performance.  With givedescriptor(), you have to create a job, get its job id, and then wait for it to start up and receive the descriptor before the execution thread can move on to handling the next connection.  This, of course, can be a performance concern.   By contrast, if you call spawn() you can continue with other tasks while the job is starting up.  Or, with sendmsg() the data is buffered, so you don't have to wait for it to be received before continuing.

The other concern is the authority issue that was mentioned at the start of this thread.

In my experience, anyone using givedescriptor/takedescriptor could save themselves some development effort by simply using inetd.  Most of the time, they are duplicating what it already does (and, often not doing it as well as inetd would!)

Does anyone have an idea why it is such a bad idea?
