Tizen Native API  5.5

The DOWNLOAD API provides functions to create and manage one or more download requests.

Required Header

#include <download.h>

Overview

The DOWNLOAD API provides functions to create and manage one or more download requests.

Major features :

  • After getting download_id from download_create(), other APIs use download_id as parameter.
  • Even if the device is off, download_id is available for 48 hours if the user does not call download_destroy().
  • Supports the callback that is called whenever the status of download changes.
  • Even if the client process is terminated, download is going on. If you want to stop a download, download_cancel() or download_destroy() should be called.
