"Formatting" is done by writing a new file system.
Could be : 'mkdosfs' or 'mkfs.ext2'.

Get a list with : 'ls -l /sbin/mk*

Example command : # mkfs.vfat /dev/sdc1

Information about the commands, e.g. : 'man mkdosfs'
And the source code, if you wish, download it,
.. then you can read the code.

How can I put 'mkfs.ext2' ot 'mkdosfs" (Linux) into C code?

Thanks
