can files be treated as streams in SYSV??

[Too hot to handle]

I have a application that needs to follow the progress of a couple of files,
I'd like to use poll for this (shaddup you tail -f ers....I've my own reasons)
the code follows that has given me a bitch...the problem is that poll says that
there is always data to read even at eof...so I have this nagging feeling that
I cannot do this with a file...blah...I have R the FM and no mention that I 
could find about not being able to treat a file like a stream...

---------------------------- code follows -----------------------------
#include <stdio.h>
#include <stropts.h>
#include <poll.h>
#define WAIT_FOR_EVENT -1

main(){
    FILE *wf0 = fopen("watch0", "a+");
    FILE *wf1 = fopen("watch1", "a+");

    struct pollfd fds[2];
    int timeout = WAIT_FOR_EVENT;
    unsigned long nfds = 2;           /* two files to watch */
    char buf[80];
    unsigned int nbyte = 80;
    int i;
    int cnt;
    int ccnt;

    fds[0].fd = fileno(wf0);
    fds[0].events = POLLIN; 

    fds[1].fd = fileno(wf1);
    fds[1].events = POLLIN;

    printf("%d %d\n", fds[0].fd, fds[1].fd);

    for(;;){
        if ((cnt = poll(fds, nfds, timeout)) > 0) {
	        printf("Event detected on %d fd(s)\n", cnt);
		fflush(stdout);
		for(i=0;i<nfds;i++){
		    if (fds[i].revents){
			ccnt = read(fds[i].fd, buf, nbyte);
			printf("fd = %d, count = %d, buf = %s\n", fds[i].fd, ccnt, buf);
			fflush(stdout);
			}
		}

        } else if cnt < 0 {
            perror("poll");
            exit(1);
        }

    }

}
