NAME
       XPAPoll -  execute existing XPA requests

SYNOPSIS
	 #include <xpa.h>

	 int XPAPoll(int msec, int maxreq);

DESCRIPTION
       It is sometimes desirable to implement a polling loop, i.e., where one checks for and processes XPA requests without blocking.  For this
       situation, use the XPAPoll() routine:

	 XPAPoll(int msec, int maxreq);

       The XPAPoll() routine will perform XPAAddSelect() and select(), but with a timeout specified in millisecs by the msec argument. If one or
       more XPA requests are made before the timeout expires, the XPAProcessSelect() routine is called to process those requests. The maxreq value
       determines how many requests will be processed: if maxreq < 0, then no events are processed, but instead, the return value indicates the
       number of events that are pending.  If maxreq == 0, then all currently pending requests will be processed.  Otherwise, up to maxreq
       requests will be processed.  (The most usual values for maxreq are 0 to process all requests and 1 to process one request).
