coreutils/lib/stdopen.c, branch v7.2

Update all copyright notices to use the newer form.

2007-07-23T12:35:58Z

Change "version 2" to "version 3" in all copyright notices.

2007-07-10T11:35:56Z

Include unconditionally, since we now assume config.h exists.

2006-08-26T06:55:57Z

Use /dev/full if possible for descriptor 0 -- like glibc now does.

2005-11-09T20:53:41Z

Fall back on /dev/null if opening /dev/full fails.

Use `#ifdef HAVE_CONFIG_H', not `#if HAVE_CONFIG_H', for consistency with gnulib.

(stdopen): Revert to iterating over descriptors, but

rather than using fstat, use fcntl with its F_GETFD flag, which is more efficient. Unlike the 2-syscall dup-close approach, this one doesn't apply any unnecessary pressure on the file descriptor pool -- thus there is one fewer way to fail.

(stdopen): Return `bool' so caller can detect failure.

Add copyright.

Include and unconditionally -- it seems to be ok to do this, these days.

Rewritten by Paul Eggert.

Now, the minimum overhead is just two system calls: dup and close.
