MKDIR(2)MKDIR(2)NAMEmkdir - make a directory file
SYNOPSIS
#include <sys/types.h>
#include <sys/stat.h>
int mkdir(const char *path, mode_t mode)
DESCRIPTION
Mkdir creates a new directory file with name path. The mode of the new
file is initialized from mode. (The protection part of the mode is
modified by the process's mode 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 that of the parent directory in
which it is created.
The low-order 9 bits of mode are modified by the process's file mode
creation mask: all bits set in the process's file mode creation mask
are cleared. See umask(2).
RETURN VALUE
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:
[ENOTDIR] A component of the path prefix is not a directory.
[ENAMETOOLONG] The path name exceeds PATH_MAX characters.
[ENOENT] A component of the path prefix does not exist.
[EACCES] Search permission is denied for a component of the path
prefix.
[ELOOP] Too many symbolic links were encountered in translating
the pathname. (Minix-vmd)
[EROFS] The named file resides on a read-only file system.
[EEXIST] The named file exists.
[ENOSPC] The directory in which the entry for the new directory
is being placed cannot be extended because there is no
space left on the file system containing the directory.
[ENOSPC] The new directory cannot be created because there there
is no space left on the file system that will contain
the directory.
[ENOSPC] There are no free inodes on the file system on which the
directory is being created.
[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.
[EFAULT] Path points outside the process's allocated address
space.
