best way to 'relay' a stream between processes

[Eslam Ahmed]

Haven't tried them personally but I guess after you create the file/pipe
using mkfifo, you will need to obtain a file descriptor for them (gint),
the sender should open it in write mode and the receiver should open it in
read mode. it has to be open at both ends simultaneously before you can
proceed to do any input or output operations on it.
