-Since glibc 2.10:
- _XOPEN_SOURCE\ >=\ 700
-.\" Other FTM combinations will also expose mknodat(), but this function was

-.SH DESCRIPTION
-The
-.BR mknodat ()
-system call operates in exactly the same way as
-.BR mknod (2),
-except for the differences described in this manual page.
-
-If the pathname given in
-.I pathname
-is relative, then it is interpreted relative to the directory
-referred to by the file descriptor
-.I dirfd
-(rather than relative to the current working directory of
-the calling process, as is done by
-.BR mknod (2)
-for a relative pathname).
-
-If
-.I pathname
-is relative and
-.I dirfd
-is the special value
-.BR AT_FDCWD ,
-then
-.I pathname
-is interpreted relative to the current working
-directory of the calling process (like
-.BR mknod (2)).
-
-If
-.I pathname
-is absolute, then
-.I dirfd
-is ignored.
-.SH RETURN VALUE
-On success,
-.BR mknodat ()
-returns 0.
-On error, \-1 is returned and
-.I errno
-is set to indicate the error.
-.SH ERRORS
-The same errors that occur for
-.BR mknod (2)
-can also occur for
-.BR mknodat ().
-The following additional errors can occur for
-.BR mknodat ():
-.TP
-.B EBADF
-.I dirfd
-is not a valid file descriptor.
-.TP
-.B ENOTDIR
-.I pathname
-is relative and
-.I dirfd
-is a file descriptor referring to a file other than a directory.
-.SH VERSIONS
-.BR mknodat ()
-was added to Linux in kernel 2.6.16;
-library support was added to glibc in version 2.4.
-.SH CONFORMING TO
-POSIX.1-2008.
-.SH NOTES
-See
-.BR openat (2)
-for an explanation of the need for
-.BR mknodat ().
