How do I know what blocks are taken and what blocks are free in UFS ?

There is something called "bitmap" in UFS, it maps logical blocks to 0
and 1 depending on type of block - free or taken. How do I retrieve
this bitmap ? Is there some ioctl around ? Also - can you provide me
with links to UFS structure description ?
