Indicate whether the following statements are true or false:

$\_\_\_\_\_\_$ Writing a message of size greater than PIPE$\_$BUF bytes to a pipe is

susceptible to being corrupted due to internal shuffling among other writes.

$\_\_\_\_\_\_$ If a process attempts to write to a pipe, but no process currently has the pipe

opened for reading, the process calling write$()$ will be terminated via

delivery of a SIGPIPE signal.

$\_\_\_\_\_\_$ If a process attempts a read$()$ on an empty pipe, and no process currently

has the pipe opened for writing, the read$()$ operation will return $0.$

$\_\_\_\_\_\_$ If a process attempts to read$()$ on a pipe containing data, and no process

currently has the pipe opened for writing, the read$()$ request will return $0.$

$\_\_\_\_\_\_$ If a process opens a FIFO using the O$\_$WRONLY flag, open$()$ will block and

wait unless$/$until a process opens the same FIFO for reading.

$\_\_\_\_\_\_$ When a process terminates, any zombie or orphaned children will be

adopted and waited on by the init $($PID $=1)$ process.

$\_\_\_\_\_\_$ A write$()$ error will occur if a process seeks past the end of a file, then

attempts to write at this location.

$\_\_\_\_\_\_$ Suppose we perform the following system call: dup$2($a$,$b$).$ If the file

descriptor referred to by b is already open, the call will fail and return $-1.$
