#### Members

`G_FILE_SET_CONTENTS_NONE`

  No guarantees about file consistency or durability. The most dangerous setting, which is slightly faster than other settings.

  - Value: `0`
  - Available since: 2.66
`G_FILE_SET_CONTENTS_CONSISTENT`

  Guarantee file consistency: after a crash, either the old version of the file or the new version of the file will be available, but not a mixture. On Unix systems this equates to an `fsync()` on the file and use of an atomic `rename()` of the new version of the file over the old.

  - Value: `1`
  - Available since: 2.66
`G_FILE_SET_CONTENTS_DURABLE`

  Guarantee file durability: after a crash, the new version of the file will be available. On Unix systems this equates to an `fsync()` on the file (if `G_FILE_SET_CONTENTS_CONSISTENT` is unset), or the effects of `G_FILE_SET_CONTENTS_CONSISTENT` plus an `fsync()` on the directory containing the file after calling `rename()`.

  - Value: `2`
  - Available since: 2.66
`G_FILE_SET_CONTENTS_ONLY_EXISTING`

  Only apply consistency and durability guarantees if the file already exists. This may speed up file operations if the file doesn’t currently exist, but may result in a corrupted version of the new file if the system crashes while writing it.

  - Value: `4`
  - Available since: 2.66
