EBackendSubprocessFactoryref_initable_backend

since: 3.16

Declaration [src]

EBackend*
e_subprocess_factory_ref_initable_backend (
  ESubprocessFactory* subprocess_factory,
  const gchar* uid,
  const gchar* backend_factory_type_name,
  const gchar* module_filename,
  GCancellable* cancellable,
  GError** error
)

Description [src]

Returns either a newly-created or existing EBackend for ESource. The returned EBackend is referenced for thread-safety and must be unreferenced with g_object_unref() when finished with it.

If the newly-created backend implements the GInitable interface, then g_initable_init() is also called on it using cancellable and error.

The subprocess_factory retains a strong reference to backend.

If no suitable EBackendFactory exists, or if the EBackend fails to initialize, the function sets error and returns NULL.

Available since: 3.16

Parameters

uid

Type: const gchar*

UID of an ESource to open.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
backend_factory_type_name

Type: const gchar*

The name of the backend factory type.

The data is owned by the caller of the method.
The value is a NUL terminated UTF-8 string.
module_filename

Type: const gchar*

The name (full-path) of the backend module to be loaded.

The data is owned by the caller of the method.

cancellable

Type: GCancellable

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 method 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.
