Two of the most fundamental functions for dealing with interprocess communication are read) and write). Consider the following otherwise valid C program int r, pipeFDs [2]; char message [512]; pidt spawnpid; pipe(pipeFDs) spawnpid fork); switch (spawnpid) case e: close(pipeFDs[]); // close the input file descriptor write(pipeFDs [1], "hi process, this is the STUFF!!", 21); break; default: close(pipeFDs [1]); // close output file descriptor r read(pipeFDs[0], message, sizeof(message ) ) ; printf("Message received from other: %s ", message); break; Select each of the following answers that is correct. The read0 call may block until data becomes available When the read) call returns, this one call will return all of the data that was sent through the pipe, which is different behavior than if this was a socket If the read) call blocks, the process will be suspended until data arrives The write) call will return before all of the data has been written, if the corresponding read) call blocks mid-transfer Pipes can fill, which will cause the write) call to block until the read) call is able to read data from the pipe
