15 For an overview of the inotify API, see inotify(7).

17 inotify_init() initializes a new inotify instance and returns a file
18 descriptor associated with a new inotify event queue.
19
20 If flags is 0, then inotify_init1() is the same as inotify_init(). The
21 following values can be bitwise ORed in flags to obtain different
22 behavior:
23
24 IN_NONBLOCK Set the O_NONBLOCK file status flag on the open file
25 description (see open(2)) referred to by the new file
26 descriptor. Using this flag saves extra calls to fcntl(2)
27 to achieve the same result.
28
29 IN_CLOEXEC Set the close-on-exec (FD_CLOEXEC) flag on the new file
30 descriptor. See the description of the O_CLOEXEC flag in
31 open(2) for reasons why this may be useful.
32
34 On success, these system calls return a new file descriptor. On error,
35 -1 is returned, and errno is set to indicate the error.
36
38 EINVAL (inotify_init1()) An invalid value was specified in flags.
39
40 EMFILE The user limit on the total number of inotify instances has been
41 reached.
42
43 EMFILE The per-process limit on the number of open file descriptors has
44 been reached.
45
46 ENFILE The system-wide limit on the total number of open files has been
47 reached.
48
49 ENOMEM Insufficient kernel memory is available.
50
52 inotify_init() first appeared in Linux 2.6.13; library support was
53 added to glibc in version 2.4. inotify_init1() was added in Linux
54 2.6.27; library support was added to glibc in version 2.9.
55
57 These system calls are Linux-specific.
