STDIN Devie File Name and Location

Hi all,
I want to know the device filename of STDIN in HPUX.
As the same is available on other platforms at /dev/ directory as "/dev/stdin", i can't find any filename for STDIN at /dev/ in HPUX.

Please let me know the name and location of device file of STDIN on HPUX.

Thanks

regards,
Srikrishna Erra.

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. IMPLEMENTATION NOTES
By default, /dev/fd is provided by devfs(5), which provides nodes for the first three file descriptors. Some sites may require nodes for additional file descriptors; these can be made available by mounting fdescfs(5) on /dev/fd. FILES
