#### Description [src]

Gets the captured data from all filtered devices for all recorded phases. The data is returned in a ZIP archive of JSON output.

Once the device has been re-inserted then the emulation data will be available using this API call.

#### Parameters

`filename`

  Type: `const gchar*`

  Archive data of JSON files.

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

  The return location for a recoverable error.

  The argument can be `NULL`.
