Reads or writes the System V shared memory segment ID starting at
position POS for size SIZE by attaching to it, copying in/out, and
detaching from it. When reading, VAR must be a variable that will
hold the data read. When writing, if STRING is too long, only SIZE
bytes are used; if STRING is too short, nulls are written to fill out
SIZE bytes. Return true if successful, or false if there is an error.
shmread() taints the variable. See also 20.8,
IPC::SysV documentation, and the
IPC::Shareable module from CPAN.
