NOTE:
if the RAM-disc allready initialized, then initRAMDisc returns with "true" without reinitialize it with the new parameters.

__io_ramdisk.startup() initialize a ramdisc of 8MB with a padding of 64kB

__io_ramdisk.shutdown () will only destroy the RAM-disk, if they from __io_ramdisk.startup () was initialized

if the ramdisc initialized from initRamDisc, then you can remount the filesystem without lost all datas

Example:

fatMount("RAM", &__io_ramdisk, 0, 0, 0);
...
fopen("RAM:/file", ...);
