hi all,
     pipes uses only direct blocks to store data. so
depending on the blocksize , a total data of
10*blocksize can be written in one go but what happens
if a writer process tries to write more 10*blocksize
of data in one go. Does the kernel overwrites the 
data  in pipe or not ? if yes, why? if not, then how
does it allow the writer to write more 10*blocksize of
data?
     if someone can direct me to implementation
(source files), it would be great.
thanks
