MKDIR(2-BSD) RISC/os Reference Manual MKDIR(2-BSD)
NAME
mkdir - make a directory file
SYNOPSIS
mkdir(path, mode)
char *path;
int 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 indi-
cates 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.
[EINVAL] The pathname contains a character with
the high-order bit set.
[ENAMETOOLONG] A component of a pathname exceeded 255
characters, or an entire path name
exceeded 1023 characters.
[ENOENT] A component of the path prefix does not
exist.
[EACCES] Search permission is denied for a com-
ponent of the path prefix.

new directory is being placed cannot be
extended because there is no space left
on the file system containing the direc-

[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.
[EDQUOT] The directory in which the entry for the
new directory is being placed cannot be
extended because the user's quota of
disk blocks on the file system contain-
ing the directory has been exhausted.
[EDQUOT] The new directory cannot be created
because the user's quota of disk blocks
on the file system that will contain the
directory has been exhausted.
[EDQUOT] The user's quota of inodes on the file
system on which the directory is being

[EIO] An I/O error occurred while making the
