Programming

i am programming in c and i need to start a procedure automatically when a cd is inserted. Anyone knows how can i do it?

thanx

Sounds like you need to create an autorun.inf file that will run your executable, which is more of a windows question than a c programming question.

no,i need to detect when a cd is inserted into the cd-rom device in order to make a c language program do certain things
i need to know if there is some kind of signal or interrupt received from a cd insert event or something similar...

Hi,

related to oomberas answer, you can start a small binary via autorun which sends you a signal.

I believe you may need to keep polling the device manually.

Have a look at this code. Most of what you will need
is here if you are using Linux, BSD, etc.

fpmurphy, that link did not work for me.

massimo_rati, you cannot have a process magically spring into existence because a cd has been inserted. You can write a daemon that will notice a cd insertion. SunOS comes with a volume manager that notices cd insertions and mounts the cd. Other versions of unix might have something similiar. This would be a problem for you. Most likely, only one such program could be running.

How this works will depend on the cd driver. You need to find the docs for your cd driver and read them.

Ideally, you will simply use open(2) on the device file for the cd. And you will not use O_NONBLOCK nor O_NDELAY. Thus the open will block until the device is ready.

But anything is possible. You're at the mercy of the driver's author.
