Name Description
G_FILE_SET_CONTENTS_NONE

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

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.

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().

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.
