Can multiple processes write to a single pipe simultaneously?
While it is possible for multiple processes to write to a single pipe simultaneously, it usually results in undesired behavior, because the data from each process can be interleaved arbitrarily. This means that if process A writes “aaa” and process B writes “bbb” to a pipe simultaneously, process C can read “ababab” from the read and of the pipe. This makes it hard to send any sort of intelligible message this way, unless there is some external synchronization mechanism for the writers. In practice, it’s best to avoid this approach. You can achieve a similar effect by having the “reader” listen on an internal port and accept “network” connections from the “writers”.
