Question fifo help !!

I have observed that the size of named pipe is always zero....
i am not understood properly we are writing something into fifo
using write() system call...then how can be it 0 ?
and will it be always 0 ?
does it due to the fact that it stores in some part of memory...
or any other reason...
what is an actual reason behind it..!!

Yup, it's always going to be 0.

A FIFO doesn't hold any data, it only a reference point to join the output of one program to the input of another. The data never actually touches the disks.
