Returns free disk space of file or directory. Argument path must be a file or directory, for example, / or .. For security reasons, path must not be a file system or ZFS pool. The function calls df(1) internally and expects sizes in 512K (FreeBSD) or 1024K (Linux) blocks.

The function returns the following error codes:

  • E_FORMAT if output format is unexpected.
  • E_NOT_FOUND if path does not exist.
  • E_PLATFORM if system type is unsupported.
  • E_READ if pipe returned no bytes.
  • E_SYSTEM if system call failed.

Arguments
