- <procedure>(filesystem
- block-size PATH)</procedure> : Returns the size of a block on the filesystem at PATH.
- <procedure>(filesystem
- blocks-total PATH)</procedure> : Returns the total number of blocks on the filesystem at PATH.
- <procedure>(filesystem
- blocks-free PATH)</procedure> : Returns the number of free blocks on the filesystem at PATH.
- <procedure>(filesystem
- blocks-available PATH)</procedure> : Returns the number of blocks available to non-root users on the filesystem at PATH.
- <procedure>(filesystem
- blocks->bytes BLOCKSIZE BLOCKS UNITS)</procedure> : Converts blocks to bytes, given the size of a block, the number of blocks, and a number representing the unit size, i.e. 1000 for kilobytes, 1024 for kibibytes.
- <procedure>(filesystem
- blocks->kilobytes BLOCKSIZE BLOCKS EXPONENT)</procedure> : Converts blocks to (kilo/mega/giga)bytes given the size of a block, the number of blocks, and an exponent representing the exponent on the unit size, i.e 1 for kilobytes, 2 for megabytes, 3 for gigabtyes, etc.
- <procedure>(filesystem
- blocks->kibibytes BLOCKSIZE BLOCKS EXPONENT)</procedure> : Converts blocks to (kibi/mebi/gibi)bytes, given the size of a block, the number of blocks, and an exponent representing the exponent on the unit size, i.e. 1 for kibibytes, 2 for mebibytes, 3 for gibigytes, etc.

### Example

The following would return the (rounded) number for gigabytes available on "/".

(filesystem:blocks->kilobytes (filesystem:block-size "/") (filesystem:blocks-available "/") 3)

### Changelog

- 1.0.1 - Dealing with bugfix in statvfs
