The read/write buffer must be soft_block_size alligned right?  The
memory allocated by malloc may not be alligned. To allign it to the
softblocksize I need to know the size. Am I missing something ???

    Thank you very much Hubert.

Regarding my second question, what I mean is, to calculate the soft 
block size of a partition on which there is no filesystem created, I am 
using the IOCTL "BLKBSZGET".

Sure - but what do you need this blocksize for?
