mkdir(S)
mkdir --
make a directory
Synopsis
#include <sys/types.h>
#include <sys/stat.h>
int mkdir(const char path, mode_t mode);
Description
mkdir creates a
new directory named by the pathname pointed to by path.
The mode of the new directory is initialized from mode
(see
chmod(S)
for the values of mode).
The protection part of the mode
argument is modified by the process's file create mask.
(See
umask(S)).
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 is a symbolic link, it is not followed.
The newly created directory is empty
with the exception
of entries for itself (.)
and its parent directory (..).
Return values
On success, mkdir returns 0 and 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.
On failure, mkdir returns -1 and sets errno to identify the error.
In the following conditions, mkdir fails and sets errno to:
EACCES-
Search permission is denied on a component of the path prefix.
EACCES-
Write permission is denied on the parent directory in which the
directory is to be created.
EEXIST-
The named file
already exists.
EFAULT-
path points outside the allocated address space of the process.
EIO-
An I/O error has occurred while accessing the file system.
ELOOP-
Too many symbolic links were encountered in translating path.
EMLINK-
The maximum number of links to the parent directory would be exceeded.
EMULTIHOP-
Components of path require hopping to multiple
remote machines
and the file system type does not allow it.
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-
path 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machine is no longer active.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.
