MKNODAT(2)		   Linux Programmers Manual		   MKNODAT(2)

       mknodat	-  create  a  special or ordinary file relative to a directory
       file descriptor

       #define _ATFILE_SOURCE
       #include  /* Definition of AT_* constants */

       int mknodat(int dirfd, const char *pathname, mode_t mode, dev_t dev);

       The mknodat() system call operates in exactly the same way as mknod(2),
       except for the differences described in this manual page.

       If  the	pathname given in pathname is relative, then it is interpreted
       relative to the directory referred to  by  the  file  descriptor  dirfd
       (rather	than  relative to the current working directory of the calling
       process, as is done by mknod(2) for a relative pathname).

       If pathname is relative and dirfd is the special value  AT_FDCWD,  then
       pathname  is  interpreted  relative to the current working directory of
       the calling process (like mknod(2)).

       If pathname is absolute, then dirfd is ignored.

       On success, mknodat() returns 0.  On error, -1 is returned and errno is
       set to indicate the error.

       The  same  errors that occur for mknod(2) can also occur for mknodat().
       The following additional errors can occur for mknodat():

       EBADF  dirfd is not a valid file descriptor.

	      pathname is relative and dirfd is a file descriptor referring to
	      a file other than a directory.

       mknodat() was added to Linux in kernel 2.6.16.

       This  system  call  is  non-standard but is proposed for inclusion in a
       future revision of POSIX.1.

       See openat(2) for an explanation of the need for mknodat().
