You'll need to be more specific about exactly what you are asking and why. Of *course* e2fsprogs needs to invoke filesystem related system calls. Just to give a few examples: e2fsck uses the blkid library to map from a LABEL specifier to a device, and this libblkid will open and read /etc/blkid.tab; e2fsck will open and read the /etc/mtab file to make sure it is not checking a mounted filesystem; e2fsck will need to open the block device and then read and write from said block device. If libntl are in use, then of course e2fsprogs will have to open and read the translation files from the filesystem --- and this is just the surface.
