File System Info Functions

From time to time, it can be useful to know certain information about the capabilities of the file system on a device. While the BVolume class provides you easy access to this information, it can occasionally be helpful to have more direct access to this information.

This section describes three C functions which can be used to obtain information about the file system on a device. One of these functions, fs_stat_dev(), returns this information given a device number. The other two functions, dev_for_path() and next_dev(), provide two ways to obtain a device number for use with fs_stat_dev().


These functions don't set errno.
