00027  * own memory in it's structure, or not. If you choose to do it yourself
00028  * you will have to pass a pointer to the memory as the last argument of
00029  * ioman_init.

00040  * calculate how many clusters it will need for that request. It then allocates
00041  * that number of new clusters to the file. Since this involves some calculations
00042  * and writing of the FAT, you might find it beneficial to limit the number of
00043  * allocations, and allow fwrite to pre-allocate a number of clusters extra.
00044  * This setting determines how many clusters will be extra allocated whenever
00045  * this is required.
00046  * Take in carefull consideration how large your clustersize is, putting 10 here
00047  * with a clustersize of 32kb means you might waste 320 kb.
00048  * The first option is for preallocating files, the other is used when enlarging
00049  * a directory to accomodate more files
