NetBSD 6.1.5 - man page for stdin (netbsd section 4)

FD(4)				   BSD Kernel Interfaces Manual 			    FD(4)

NAME
     fd, stdin, stdout, stderr -- file descriptor files

DESCRIPTION
     The files /dev/fd/0 through /dev/fd/# refer to file descriptors which can be accessed
     through the file system.  If the file descriptor is open and the mode the file is being
     opened with is a subset of the mode of the existing descriptor, the call:

	   fd = open("/dev/fd/0", mode);

     and the call:

	   fd = fcntl(0, F_DUPFD, 0);

     are equivalent.

     Opening the files /dev/stdin, /dev/stdout and /dev/stderr is equivalent to the following
     calls:

	   fd = fcntl(STDIN_FILENO,  F_DUPFD, 0);
	   fd = fcntl(STDOUT_FILENO, F_DUPFD, 0);
	   fd = fcntl(STDERR_FILENO, F_DUPFD, 0);

     Flags to the open(2) call other than O_RDONLY, O_WRONLY and O_RDWR are ignored.

FILES
     /dev/fd/#
     /dev/stdin
     /dev/stdout
     /dev/stderr
