creating iso image programmatically from a file descriptor

rohini447 · 06-09-2011, 10:44 AM

Could anyone please let me know if there is any library call or system call in SuSE that can be used to create an iso image out of a file. My requirement is to create a isoimage given the file descriptor(not the filename) of the file.

Regards,

Building an iso image is a non-trivial task, so you won't find this in a single system call.

If you wish to use a library to construct the image, consider one such as libiso9660, which is part of libcdio.

If you need a quick and dirty approach, just copy the file to a named temporary file (eg in /tmp) and exec genisoimage from the main application.

Thank you neonsignal. I would go through the links you provided. The application in question is currently using mkisofs which accepts a file name instead of descriptor.
