NAME
feof - determine if end-of-file flag is set
SYNOPSIS
feof(fd)
TYPES
fd file stream open for reading
return 0 or 1
DESCRIPTION
The function feof(fd) returns 1 or 0 according as the end-of-file flag
is set or clear.
The end-of-file flag for the stream fd is set if reading at the
end-of-file position is attempted. The flag is cleared by
positioning operations (fseek, rewind, fsetpos) and by freopen.
EXAMPLE
> fd1 = fopen("/tmp/newfile", "w")
> fputs(fd1, "Chongo was here\n")
> fflush(fd1)
> fd2 = fopen("/tmp/newfile", "r")
> feof(fd2)
0
> fgetline(fd2)
"Chongo was here"
> feof(fd2)
0
> fgetline(fd2)
> feof(fd2)
