/* Cluster pre-allocation
|
|
----------------------

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

-----------------------

* reporting here. This is optional, the costs are 1 byte per object,
|
|
* and a small increase in code size.
|
|
* You can enable error recording for all object, or you can select the
|
|
* object manually.
