MKDIRAT(2)		   Linux Programmers Manual		   MKDIRAT(2)

       mkdirat - create a directory relative to a directory file descriptor

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

       int mkdirat(int dirfd, const char *pathname, mode_t mode);

       The mkdirat() system call operates in exactly the same way as mkdir(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 mkdir(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 mkdir(2)).

       If pathname is absolute, then dirfd is ignored.

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

       The same errors that occur for mkdir(2) can also occur  for  mkdirat().
       The following additional errors can occur for mkdirat():

       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.

       mkdirat() 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 mkdirat().
