One practical usage is while using Linux USB file-storage gadget driver. When you want to access data written by USB host on regular file on gadget itself, you can do losetup on the regular file. After associating loop device to regular file, the device becomes valid block device allowing you to perform mount, unmount, read , write etc. operations. Reference: http://www.linux-usb.org/gadget/file_storage.html
I don't know exactly, but another usage of it is in while creating iso image of data. -- Kalpesh On Mon, Oct 20, 2008 at 3:41 PM, Sandeep K Sinha <[EMAIL PROTECTED]>wrote: > Hi Rishi, > > You can now do a mkfs on that particular file, mount it and do > whatever you can do with a normal block device. > > Read more about "loopback devices". > > > > On Mon, Oct 20, 2008 at 3:28 PM, rishi agrawal <[EMAIL PROTECTED]> > wrote: > > > > Hello Everyone, > > > > I would like to know about the use of "losetup". > > > > Also, try googling for "Hari Paranjape + Device Mappers". > > > By use I want mean that in what all situations will I use losetup.
