mkdir(2)
mkdir(2) System Calls mkdir(2)
NAME
mkdir, mkdirat - make a directory relative to directory file descriptor
SYNOPSIS
#include <sys/stat.h>
int mkdir(const char *path, mode_t mode);
int mkdirat(int fd, const char *path, mode_t mode);
DESCRIPTION
The mkdir() function creates a new directory named by the path name
pointed to by path. The mode of the new directory is initialized from
mode (see chmod(2) for values of mode). The access permission bits
(S_IAMB) of the mode argument is modified by the process's file cre‐
ation mask (see umask(2)).
The directory's owner ID is set to the process's effective user ID. The
directory's group ID is set to the process's effective group ID, or if
the S_ISGID bit is set in the parent directory, then the group ID of
the directory is inherited from the parent. The S_ISGID bit of the new
directory is inherited from the parent directory.
If path names a symbolic link, mkdir() fails and sets errno to EEXIST.
The newly created directory is empty with the exception of entries for
itself (.) and its parent directory (..).
Upon successful completion, mkdir() marks for update the st_atime,
st_ctime and st_mtime fields of the directory. Also, the st_ctime and
st_mtime fields of the directory that contains the new entry are marked
for update.
The mkdirat() function is equivalent to the mkdir() function except in
the case where path specifies a relative path. In this case the newly
created directory is created relative to the directory associated with
the file descriptor fd instead of the current working directory. If the
file descriptor was opened without O_SEARCH, the function checks
whether directory searches are permitted using the current permissions
of the directory underlying the file descriptor. If the file descriptor
was opened with O_SEARCH, the function does not perform the check.
If mkdirat() is passed the special value AT_FDCWD in the fd parameter,
the current working directory is used and the behavior is identical to
a call to mkdir().
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, −1 is returned,
no directory is created, and errno is set to indicate the error.
ERRORS
The mkdir() and mkdirat() functions will fail if:
EACCES Either a component of the path prefix denies search
permission or write permission is denied on the parent
directory of the directory to be created.
EDQUOT The directory where the new file entry is being placed
cannot be extended because the user's quota of disk
blocks on that file system has been exhausted; the new
directory cannot be created because the user's quota of
disk blocks on that file system has been exhausted; or
the user's quota of inodes on the file system where the
file is being created has been exhausted.
EEXIST The named file already exists.
EFAULT The path argument points to an illegal address.
EINVAL An attempt was made to create an extended attribute
that is a directory.
EIO An I/O error has occurred while accessing the file sys‐
tem.
EILSEQ The path argument includes non-UTF8 characters and the
file system accepts only file names where all charac‐
ters are part of the UTF-8 character codeset.
ELOOP Too many symbolic links were encountered in translating
path, or a loop exists in symbolic links encountered
during resolution of path
EMLINK The maximum number of links to the parent directory
would be exceeded.
ENAMETOOLONG The length of the path argument exceeds PATH_MAX, or
the length of a path component exceeds NAME_MAX while
_POSIX_NO_TRUNC is in effect.
ENOENT A component of the path prefix does not exist or is a
null pathname.
ENOLINK The path argument points to a remote machine and the
link to that machine is no longer active.
ENOSPC No free space is available on the device containing the
directory.
ENOTDIR A component of the path prefix is not a directory.
EROFS The path prefix resides on a read-only file system.
The mkdirat() function will fail if:
EBADF The path argument does not specify an absolute path and the fd
argument is neither AT_FDCWD nor a valid file descriptor open
for reading.
The mkdir() and mkdirat() functions may fail if:
ELOOP More than {SYMLOOP_MAX} symbolic links were encountered
during resolution of the path argument.
ENAMETOOLONG As a result of encountering a symbolic link in resolu‐
tion of the path argument, the length of the substi‐
tuted pathname string exceeded {PATH_MAX}.
The mkdirat() function may fail if:
ENOTDIR The path argument is not an absolute path and fd is neither
AT_FDCWD nor a file descriptor associated with a directory.
EXAMPLES
Example 1 Create a directory.
The following example demonstrates how to create a directory named
/home/cnd/mod1, with read, write, and search permissions for owner and
group, and with read and search permissions for others.
#include <sys/stat.h>
int status;
...
status = mkdir("/home/cnd/mod1",
S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH);

HISTORY
The mkdir() function has been included in all Sun and Oracle releases
of Solaris.
The mkdirat() function was added to Solaris in the Solaris 11.0
release.
