Description: Reference for Gio.SettingsSchemaSource.new_from_directory

### Function

# Gio SettingsSchemaSourcenew_from_directory

since: 2.32

#### Declaration

    GSettingsSchemaSource*
    g_settings_schema_source_new_from_directory (
      const gchar* directory,
      GSettingsSchemaSource* parent,
      gboolean trusted,
      GError** error
    )

#### Description

Attempts to create a new schema source corresponding to the contents of the given directory.

This function is not required for normal uses of `GSettings` but it may be useful to authors of plugin management systems.

The directory should contain a file called `gschemas.compiled` as produced by the [glib-compile-schemas][glib-compile-schemas] tool.

If `trusted` is `TRUE` then `gschemas.compiled` is trusted not to be corrupted. This assumption has a performance advantage, but can result in crashes or inconsistent behaviour in the case of a corrupted file. Generally, you should set `trusted` to `TRUE` for files installed by the system and to `FALSE` for files in the home directory.

In either case, an empty file or some types of corruption in the file will result in `G_FILE_ERROR_INVAL` being returned.

If `parent` is non-`NULL` then there are two effects.

First, if `g_settings_schema_source_lookup()` is called with the `recursive` flag set to `TRUE` and the schema can not be found in the source, the lookup will recurse to the parent.

Second, any references to other schemas specified within this source (ie: `child` or `extends`) references may be resolved from the `parent`.

For this second reason, except in very unusual situations, the `parent` should probably be given as the default schema source, as returned by g_settings_schema_source_get_default().

Available since: 2.32

#### Parameters

`directory`

  Type: `const gchar*`

  The filename of a directory.

  The data is owned by the caller of the function.
  The value is a file system path, using the OS encoding.

`parent`

  Type: `GSettingsSchemaSource`

  A `GSettingsSchemaSource`, or `NULL`.

  The argument can be `NULL`.
  The data is owned by the caller of the function.

`trusted`

  Type: `gboolean`

  `TRUE`, if the directory is trusted.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `GSettingsSchemaSource`

No description available.

The caller of the function takes ownership of the data, and is responsible for freeing it.
