Detailed Description

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