\begin{funcdesc}{mknod}{path\optional{, mode=0600, major, minor}}
Create a filesystem node (file, device special file or named pipe)
named filename. mode specifies both the permissions to use and the
type of node to be created, being combined (bitwise OR) with one of
S_IFREG, S_IFCHR, S_IFBLK, and S_IFIFO (those constants are available

newly created device special file, otherwise they are ignored.
