+  NAME
+
+	poll - select(2)-based poll() emulation function for BSD systems.
+
+  SYNOPSIS
+	#include "poll.h"
+
+	struct pollfd
+	{
+	    int     fd;
+	    short   events;
+	    short   revents;
+	}
+
+	int poll (struct pollfd *pArray, unsigned long n_fds, int timeout)
+
+  DESCRIPTION
+
+	This file, and the accompanying "poll.c", implement the System V
+	poll(2) system call for BSD systems (which typically do not provide
+	poll()).  Poll() provides a method for multiplexing input and output
+	on multiple open file descriptors; in traditional BSD systems, that
+	capability is provided by select().  While the semantics of select()
+	differ from those of poll(), poll() can be readily emulated in terms
+	of select() -- which is how this function is implemented.
