GError** error

Description [src]
Saves one component into the remote side. The instances contain the master
object and all the detached instances of the same component (all have the same UID).
When the overwrite_existing is TRUE, then the descendant can overwrite an object
with the same UID on the remote side (usually used for modify). The conflict_resolution
defines what to do when the remote side had made any changes to the object since
the last update.
The descendant can use e_cal_meta_backend_merge_instances() to merge
the instances into one VCALENDAR component, which will contain also
used time zones.
The components in instances have already converted locally stored attachments
into inline attachments, thus it’s not needed to call
e_cal_meta_backend_inline_local_attachments_sync() by the descendant.
The out_new_uid can be populated with a UID of the saved component as the server
assigned it to it. This UID, if set, is loaded from the remote side afterwards,
also to see whether any changes had been made to the component by the remote side.
The out_new_extra can be populated with a new extra data to save with the component.
Left it NULL, to keep the same value as the extra.
The descendant can use an #E_CLIENT_ERROR_OUT_OF_SYNC error to indicate that
the save failed due to made changes on the remote side, and let the meta_backend
to resolve this conflict based on the conflict_resolution on its own.
The #E_CLIENT_ERROR_OUT_OF_SYNC error should not be used when the descendant
is able to resolve the conflicts itself.
It is mandatory to implement this virtual method by the writable descendant.

Parameters
overwrite_existing-
Type:
gbooleanTRUEwhen can overwrite existing components,FALSEotherwise. conflict_resolution-
Type:
EConflictResolutionOne of
EConflictResolution, what to do on conflicts. instances-
Type: A list of
NoneInstances of the component to save.
The data is owned by the caller of the method. extra-
Type:
const gchar*Extra data saved with the components in an
ECalCache.The argument can be NULL.The data is owned by the caller of the method. The value is a NUL terminated UTF-8 string. opflags-
Type:
ECalOperationFlagsBit-or of
ECalOperationFlags. out_new_uid-
Type:
gchar**Return location for the UID of the saved component.
The argument will be set by the function. The caller of the method takes ownership of the returned data, and is responsible for freeing it. The value is a NUL terminated UTF-8 string. out_new_extra-
Type:
gchar**Return location for the extra data to store with the component.
The argument will be set by the function. The caller of the method takes ownership of the returned data, and is responsible for freeing it. The value is a NUL terminated UTF-8 string. cancellable-
Type:
GCancellableOptional
GCancellableobject, orNULL.The argument can be NULL.The data is owned by the caller of the method. 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 aNULLGError*.The argument will be left initialized to NULLby the virtual 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.
