.Sh SYNOPSIS
.In sys/types.h
.In sys/stat.h
.Ft int
.Fn mkdir "const char *path" "mode_t mode"
.Sh DESCRIPTION
The directory
.Fa path
is created with the access permissions specified by
.Fa mode
and restricted by the
.Xr umask 2
of the calling process.
.Pp
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.
.Sh RETURN VALUES
.Rv -std mkdir
.Sh ERRORS
The
.Fn mkdir
system call
will fail and no directory will be created if:
.Bl -tag -width Er
.It Bq Er ENOTDIR
A component of the path prefix is not a directory.
.It Bq Er ENAMETOOLONG
A component of a pathname exceeded 255 characters,
or an entire path name exceeded 1023 characters.
.It Bq Er ENOENT
A component of the path prefix does not exist.
.It Bq Er EACCES
Search permission is denied for a component of the path prefix,
or write permission is denied
on the parent directory of the directory to be created.
.It Bq Er ELOOP
Too many symbolic links were encountered in translating the pathname.
.It Bq Er EPERM
The parent directory of the named file has its immutable flag set, see the
.Xr chflags 2
manual page for more information.
.It Bq Er EROFS
The named file resides on a read-only file system.
.It Bq Er EEXIST
The named file exists.
.It Bq Er ENOSPC
The new directory cannot be created because there is no space left
on the file system that will contain the directory.
.It Bq Er ENOSPC
There are no free inodes on the file system on which the
directory is being created.
.It Bq Er 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.
.It Bq Er EDQUOT
The user's quota of inodes on the file system on
which the directory is being created has been exhausted.
.It Bq Er EIO
An I/O error occurred while making the directory entry or allocating the inode.
.It Bq Er EIO
An I/O error occurred while reading from or writing to the file system.
.It Bq Er EFAULT
The
.Fa path
argument
points outside the process's allocated address space.
.El
.Sh SEE ALSO
