CD-R or CD-RW ?

[kielhd]

Hi NG,

is there a way for Perl to find out, if a CD is a CD-R or a CD-RW?

TIA,
Henning

If your operating system provides and interface that makes this
information available to applications then no doubt you can get at it
with Perl.

For example on Unix-like OSs there's probably an IOCTL you can use on
the device file correspoding to the CD.

Is the OP talking about the disc or the drive? Linux (and therefore
Solaris probably too) has the CDROM_GET_CAPABILITY ioctl which, among
other things, tells whether a drive can write CD-Rs, CD-RWs, DVD-Rs
and/or DVD-RWs. But I know of no ioctl that would tell me whether an
inserted disc is CD-R or CD-RW.
