#### Parameters

`sexp`

  Type: `const gchar*`

  Search expression; use `NULL` or an empty string to list all stored components.

  The argument can be `NULL`.
  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`func`

  Type: `ECalCacheSearchFunc`

  An `ECalCacheSearchFunc` callback to call for each row which satisfies `sexp`.

`user_data`

  Type: `gpointer`

  User data for `func`.

  The argument can be `NULL`.
  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`.
