41 initializes a new inotify instance and returns a file descriptor associated
42 with a new inotify event queue.
50 The following values can be bitwise ORed in
52 to obtain different behavior:
57 file status flag on the new open file description.
58 Using this flag saves extra calls to
60 to achieve the same result.
65 flag on the new file descriptor.
66 See the description of the
70 for reasons why this may be useful.
72 On success, these system calls return a new file descriptor.
73 On error, \-1 is returned, and
75 is set to indicate the error.
