When I use a read call reading from a pipe, the read takes a long time to
return.

Why does this happen?

Thanks,

Pipes are buffered. The reader will have to wait until the
pipe is full before anything falls out the end. You may be
able to use setbuf() after creating the pipe to turn off
buffering. YMMV.
