EDataCal.CalBackend.send_objects_sync

### Method

# EDataCal CalBackendsend_objects_sync

since: 3.10

#### Declaration [src]

    gchar*
    e_cal_backend_send_objects_sync (
      ECalBackend* backend,
      const gchar* calobj,
      ECalOperationFlags opflags,
      GQueue* out_users,
      GCancellable* cancellable,
      GError** error
    )

#### Description [src]

Sends meeting information in `calobj`. The `backend` may modify `calobj` and send meeting information only to particular users. The function returns the (maybe) modified `calobj` and deposits the list of users the meeting information was sent (to be send) to in `out_users`.

The returned pointer should be freed with g_free(), when no londer needed.

If an error occurs, the function will set `error` and return `NULL`.

Available since: 3.10

#### Parameters

`calobj`

  Type: `const gchar*`

  An iCalendar string.

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

`opflags`

  Type: `ECalOperationFlags`

  Bit-or of `ECalOperationFlags`.

`out_users`

  Type: `GQueue`

  A `GQueue` in which to deposit results.

  The data is owned by the caller of the method.

`cancellable`

  Type: `GCancellable`

  Optional `GCancellable` object, or `NULL`.

  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 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.

#### Return value

Type: `gchar*`

A vCalendar string, or `NULL` on error.

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.
