DESCRIPTION
mkdir
() attempts to create a
directory named pathname
.
The argument mode
specifies the mode for the new directory (see inode(7)). It is modified
by the process_zsingle_quotesz_s umask
in the
usual way: in the absence of a default ACL, the mode of the
created directory is (mode
& ~umask
& 0777). Whether other mode
bits are honored for the
created directory depends on the operating system. For Linux,
see NOTES below.
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 (mount -o bsdgroups or, synonymously 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.
If the parent directory has the set-group-ID bit set, then so will the newly created directory.
mkdirat()
The mkdirat
() system call
operates in exactly the same way as mkdir
(), except for the differences
described here.
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
() 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
()).
If pathname
is
absolute, then dirfd
is ignored.
See openat(2) for an
explanation of the need for mkdirat
().
RETURN VALUE
mkdir
() and mkdirat
() return zero on success, or
−1 if an error occurred (in which case, errno
is set appropriately).
ERRORS
- EACCES
-
The parent directory does not allow write permission to the process, or one of the directories in
pathname
did not allow search permission. (See also path_resolution(7).) - EDQUOT
-
The user_zsingle_quotesz_s quota of disk blocks or inodes on the filesystem has been exhausted.
- EEXIST
-
pathname
already exists (not necessarily as a directory). This includes the case wherepathname
is a symbolic link, dangling or not. - EFAULT
-
pathname
points outside your accessible address space. - EINVAL
-
The final component (basename) of the new directory_zsingle_quotesz_s
pathname
is invalid (e.g., it contains characters not permitted by the underlying filesystem). - ELOOP
-
Too many symbolic links were encountered in resolving
pathname
. - EMLINK
-
The number of links to the parent directory would exceed
LINK_MAX
. - ENAMETOOLONG
-
pathname
was too long. - ENOENT
-
A directory component in
pathname
does not exist or is a dangling symbolic link. - ENOMEM
-
Insufficient kernel memory was available.
- ENOSPC
-
The device containing
pathname
has no room for the new directory. - ENOSPC
-
The new directory cannot be created because the user_zsingle_quotesz_s disk quota is exhausted.
- ENOTDIR
-
A component used as a directory in
pathname
is not, in fact, a directory. - EPERM
-
The filesystem containing
pathname
does not support the creation of directories. - EROFS
-
pathname
refers to a file on a read-only filesystem.
The following additional errors can occur for mkdirat
():
- EBADF
-
dirfd
is not a valid file descriptor. - ENOTDIR
-
pathname
is relative anddirfd
is a file descriptor referring to a file other than a directory.
VERSIONS
mkdirat
() was added to Linux
in kernel 2.6.16; library support was added to glibc in
version 2.4.
NOTES
Under Linux, apart from the permission bits, the
S_ISVTX
mode
bit is also honored.
There are many infelicities in the protocol underlying
NFS. Some of these affect mkdir
().
