6 inotify_init, inotify_init1 - initialize an inotify instance
7
9 #include <sys/inotify.h>
10
11 int inotify_init(void);
12 int inotify_init1(int flags);
13
15 inotify_init() initializes a new inotify instance and returns a file
16 descriptor associated with a new inotify event queue.
17
18 If flags is 0, then inotify_init1() is the same as inotify_init(). The
19 following values can be bitwise ORed in flags to obtain different
20 behavior:
21
22 IN_NONBLOCK Set the O_NONBLOCK file status flag on the new open file
23 description. Using this flag saves extra calls to fcntl(2)
24 to achieve the same result.
25
26 IN_CLOEXEC Set the close-on-exec (FD_CLOEXEC) flag on the new file
27 descriptor. See the description of the O_CLOEXEC flag in
28 open(2) for reasons why this may be useful.
29
31 On success, these system calls return a new file descriptor. On error,
32 -1 is returned, and errno is set to indicate the error.
33
35 EINVAL (inotify_init1()) An invalid value was specified in flags.
36
37 EMFILE The user limit on the total number of inotify instances has been
38 reached.
39
40 ENFILE The system limit on the total number of file descriptors has
41 been reached.
42
43 ENOMEM Insufficient kernel memory is available.
44
46 inotify_init() first appeared in Linux 2.6.13. inotify_init1() was
47 added in Linux 2.6.27.
48
50 These system calls are Linux-specific.
