Information for C program interfaces

This section describes special aspects when accessing files of bs2fs file systems via program interfaces.

You can use the sysfs interface (see the "C Library Functions for POSIX Applications" manual and "sysfs - query information about the file system type") to determine whether bs2fs file systems are supported in an existing POSIX installation.

You can check whether a bs2fs file system is mounted using the mount commandor by searching the mount table /etc/mnttab (see "/etc/mnttab - table of the mounted file systems"). For each mounted file system this table contains an entry with the data of this file system.
