fdescfs - file-descriptor file system
fdescfs /dev/fd fdescfs rw 0 0
The file system's contents appear as a list of numbered files which correspond to the open files of the process reading the directory. 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.
Flags to the open(2) call other than O_RDONLY O_WRONLY and O_RDWR are ignored.
"mount -t fdescfs null /dev/fd"
