Linux-C: reading from pipe returns first buffer written to it

c++ fork inter-process-communicat linux pipe

This program simulates a variant of Dijkstra’s Producer/Consumer problem. A pipeline is first created followed by a child process using fork(). The child will then write to the pipe a crudely done randomly generated piece of “stock market ticker information”. After waiting for the child/producer process to write this information, the parent/consumer process will read it out. The first output

Proper implementation of an inter process communication (IPC)

Is the following a proper implementation of an inter-process communication? It seems to be working but I’m wondering if there could be a race condition leading to hanging. One constraint is that both processes need to be started independently and in any order. Answer Some stress tests showed no problem so the implementation seems OK if somebody wants to reuse
