Specifies both the permissions to use and the type of node to be
created. It should be a combination (using bitwise OR) of one of the
file types listed below and the permissions for the new node(e.g. 0640).
Possible file types are: <constant>EIO_S_IFREG</constant>(regular file),
<constant>EIO_S_IFCHR</constant>(character file),
<constant>EIO_S_IFBLK</constant>(block special file),
<constant>EIO_S_IFIFO</constant>(FIFO - named pipe) and
<constant>EIO_S_IFSOCK</constant>(UNIX domain socket).
To specify permissions <emphasis>EIO_S_I*</emphasis> constants could be
used.
