/** @defgroup MediaMan Media_Manager

 * 
 *  Mediaman enables users to access the UMD drive. The drive can be accessed through files or sectors. \n
 * 
 *  To access the UMD drive via a file, the PSP provides the ISO-9660 file system. A file can be accessed \n
 *  by standard I/O functions as in sceIoOpen(), sceIoClose() and sceIoRead(). The general path format is the \n
 *  following: "device alias name" + "unit number" + ":" + "file path name". Here, the device alias name and \n
 *  the unit number are set by the sceUmdActivate() function ("disc0:" being the standard). \n
 *  To open a file, consider this example: \n
 *      sceIoOpen("disc0:PSP_GAME/EXAMPLEDIR/examplefile.exp"); \n
 * 
 *  To access the UMD drive by sectors, the PSP provides a UMD block device driver. You can read the sectors \n
 *  by using standard I/O functions (i.e. sceIoOpen(), sceIoClose() and sceIoRead()). The general path format \n
 *  is the following: "block device name" + "unit number" + ':'. Note that the block device is set by the \n
 *  sceUmdActivate() function to "umd0:". \n
 *  To open a phyisical device as a device file, consider this example: \n
 *      sceIoOpen("UMD0:...."); \n
 *  By default, opening a new physical device sets the first sector to read at sector_0. \n
 * 
 *  A sector contains 2048 bytes and reading is performed sector wise. That is, in sceIoRead() the read size \n
 *  has to be specified in the number of sectors you want to read. \n
