MKDIR(2) BSD System Calls Manual MKDIR(2)

NAME mkdir -- make a directory file

SYNOPSIS #include <sys/stat.h>

 int
 **mkdir**(const char *path, mode**_**t mode);

DESCRIPTION The directory path is created with the access permissions specified by mode and restricted by the umask(2) of the calling process.

 The directory's owner ID is set to the process's effective user ID.  The
 directory's group ID is set to that of the parent directory in which it
 is created.

RETURN VALUES A 0 return value indicates success. A -1 return value indicates an error, and an error code is stored in errno.

ERRORS Mkdir() will fail and no directory will be created if:

 [EACCES]           Search permission is denied for a component of the
                    path prefix.

 [EACCES]           Write permission is denied for the parent directory.

 [EDQUOT]           The new directory cannot be created because the user's
                    quota of disk blocks on the file system that will con-tain contain
                    tain the directory has been exhausted.

 [EDQUOT]           The user's quota of inodes on the file system on which
                    the directory is being created has been exhausted.

 [EEXIST]           The named file exists.

 [EFAULT]           Path points outside the process's allocated address
                    space.

 [EIO]              An I/O error occurred while making the directory entry
                    or allocating the inode.

 [EIO]              An I/O error occurred while reading from or writing to
                    the file system.

 [ELOOP]            Too many symbolic links were encountered in translat-ing translating
                    ing the pathname.  This is taken to be indicative of a
                    looping symbolic link.

 [EMLINK]           The parent directory already has {LINK_MAX} links.

 [ENAMETOOLONG]     A component of a pathname exceeded {NAME_MAX} charac-ters, characters,
                    ters, or an entire path name exceeded {PATH_MAX} char-acters. characters.
                    acters.

 [ENOENT]           A component of the path prefix does not exist or path
                    is an empty string.

 [ENOSPC]           The new directory cannot be created because there is
                    no space left on the file system that would contain
                    it.

 [ENOSPC]           There are no free inodes on the file system on which
                    the directory is being created.

 [ENOTDIR]          A component of the path prefix is not a directory.

 [EROFS]            The parent directory resides on a read-only file sys-tem. system.
                    tem.
