Subject: Possible misbehavior of write
Precedence: bulk

Is there a "correct" thing for write() to do when passed a null buffer? This
code:

write(fd,NULL,count);

...assuming reasonable values for fd and count, under Linux returns -1 and
sets errno to EFAULT ("Bad address"). Under djgpp, however, it sends a
SIGSEGV. Is this correct? What does POSIX / ANSI have to say?
