+.SH DESCRIPTION
+.BR mkdir ()
+attempts to create a directory named
+.IR pathname .
+.P
+The argument
+.I mode
+specifies the mode for the new directory (see
+.BR inode (7)).
+It is modified by the process's
+.I umask
+in the usual way: in the absence of a default ACL, the mode of the
+created directory is
+.RI ( mode " & \[ti]" umask " & 0777)."
+Whether other
+.I mode
+bits are honored for the created directory depends on the operating system.
+For Linux, see NOTES below.
+.P
+The newly created directory will be owned by the effective user ID of the
+process.
+If the directory containing the file has the set-group-ID
+bit set, or if the filesystem is mounted with BSD group semantics
+.RI ( "mount \-o bsdgroups"
+or, synonymously
+.IR "mount \-o grpid" ),
+the new directory will inherit the group ownership from its parent;
+otherwise it will be owned by the effective group ID of the process.
+.P
+If the parent directory has the set-group-ID bit set, then so will the
+newly created directory.

+.SS mkdirat()
+The
+.BR mkdirat ()
+system call operates in exactly the same way as
+.BR mkdir (),
+except for the differences described here.
+.P
+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 mkdir ()
+for a relative pathname).
+.P
+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 mkdir ()).
+.P
+If
+.I pathname
+is absolute, then
+.I dirfd
+is ignored.
+.P
+See
+.BR openat (2)
+for an explanation of the need for
+.BR mkdirat ().
+.SH RETURN VALUE
+.BR mkdir ()
+and
+.BR mkdirat ()
+return zero on success.
+On error, \-1 is returned and
+.I errno
+is set to indicate the error.
+.SH ERRORS
+.TP
+.B EACCES
+The parent directory does not allow write permission to the process,
+or one of the directories in
+.I pathname
+did not allow search permission.
+(See also
+.BR path_resolution (7).)
+.TP
+.B EBADF
+.RB ( mkdirat ())
+.I pathname
+is relative but
+.I dirfd
+is neither
+.B AT_FDCWD
+nor a valid file descriptor.
+.TP
+.B EDQUOT
+The user's quota of disk blocks or inodes on the filesystem has been
+exhausted.
+.TP
+.B EEXIST
+.I pathname
+already exists (not necessarily as a directory).
+This includes the case where
+.I pathname
+is a symbolic link, dangling or not.
+.TP
+.B EFAULT
+.IR pathname " points outside your accessible address space."
+.TP
+.B EINVAL
+The final component ("basename") of the new directory's
+.I pathname
+is invalid
+(e.g., it contains characters not permitted by the underlying filesystem).
+.TP
+.B ELOOP
+Too many symbolic links were encountered in resolving
+.IR pathname .
+.TP
+.B EMLINK
+The number of links to the parent directory would exceed
+.BR LINK_MAX .
+.TP
+.B ENAMETOOLONG
+.IR pathname " was too long."
+.TP
+.B ENOENT
+A directory component in
+.I pathname
+does not exist or is a dangling symbolic link.
+.TP
+.B ENOMEM
+Insufficient kernel memory was available.
+.TP
+.B ENOSPC
+The device containing
+.I pathname
+has no room for the new directory.
+.TP
+.B ENOSPC
+The new directory cannot be created because the user's disk quota is
+exhausted.
+.TP
+.B ENOTDIR
+A component used as a directory in
+.I pathname
+is not, in fact, a directory.
+.TP
+.B ENOTDIR
+.RB ( mkdirat ())
+.I pathname
+is relative and
+.I dirfd
+is a file descriptor referring to a file other than a directory.
+.TP
+.B EPERM
+The filesystem containing
+.I pathname
+does not support the creation of directories.
+.TP
+.B EROFS
+.I pathname
+refers to a file on a read-only filesystem.
+.SH VERSIONS
+Under Linux, apart from the permission bits, the
+.B S_ISVTX
+.I mode
+bit is also honored.
+.SS glibc notes
+On older kernels where
+.BR mkdirat ()
+is unavailable, the glibc wrapper function falls back to the use of
+.BR mkdir ().
+When
+.I pathname
+is a relative pathname,
+glibc constructs a pathname based on the symbolic link in
+.I /proc/self/fd
+that corresponds to the
+.I dirfd
+argument.
+.SH STANDARDS
+POSIX.1-2008.
+.SH HISTORY
+.TP
+.BR mkdir ()
+SVr4, BSD, POSIX.1-2001.
+.\" SVr4 documents additional EIO, EMULTIHOP
+.TP
+.BR mkdirat ()
+Linux 2.6.16,
+glibc 2.4.
+.SH NOTES
+There are many infelicities in the protocol underlying NFS.
+Some of these affect
+.BR mkdir ().
