In article <171 at ecrcvax.UUCP> snoopy at ecrcvax.UUCP (Sebastian Schmitz)
describes how little is assured by the successful return of a write
system call. What is said is correct, but does NOT apply to I/O
on raw devices. A successful write on a raw device guarantees that
your data has reached the peripheral. Whether it has been indelibly
inscribed depends on the device.
