SettingsBackend.keyfileSettingsBackendNew

Creates a keyfile-backed #GSettingsBackend.

The filename of the keyfile to use is given by @filename.

All settings read to or written from the backend must fall under the path given in @root_path (which must start and end with a slash and not contain two consecutive slashes). @root_path may be "/".

If @root_group is non-%NULL then it specifies the name of the keyfile group used for keys that are written directly below @root_path. For example, if @root_path is "/apps/example/" and @root_group is "toplevel", then settings the key "/apps/example/enabled" to a value of %TRUE will cause the following to appear in the keyfile:

|[ toplevel

enabled=true ]|

If @root_group is %NULL then it is not permitted to store keys directly below the @root_path.

For keys not stored directly below @root_path (ie: in a sub-path), the name of the subpath (with the final slash stripped) is used as the name of the keyfile group. To continue the example, if "/apps/example/profiles/default/font-size" were set to 12 then the following would appear in the keyfile:

|[ [profiles/default] font-size=12 ]|

The backend will refuse writes (and return writability as being %FALSE) for keys outside of @root_path and, in the event that @root_group is %NULL, also for keys directly under @root_path. Writes will also be refused if the backend detects that it has the inability to rewrite the keyfile (ie: the containing directory is not writable).

There is no checking done for your key namespace clashing with the syntax of the key file format. For example, if you have '[' or ']' characters in your path names or '=' in your key names you may be in trouble.
