INOTIFY_INIT(2)           Linux Programmer's Manual          INOTIFY_INIT(2)

NAME         top

       inotify_init, inotify_init1 - initialize an inotify instance

SYNOPSIS         top

       #include <sys/inotify.h>

       int inotify_init(void);
       int inotify_init1(int flags);

DESCRIPTION         top

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

       inotify_init() initializes a new inotify instance and returns a file
       descriptor associated with a new inotify event queue.

       If flags is 0, then inotify_init1() is the same as inotify_init().
       The following values can be bitwise ORed in flags to obtain different

       IN_NONBLOCK Set the O_NONBLOCK file status flag on the new open file
                   description.  Using this flag saves extra calls to
                   fcntl(2) to achieve the same result.

       IN_CLOEXEC  Set the close-on-exec (FD_CLOEXEC) flag on the new file
                   descriptor.  See the description of the O_CLOEXEC flag in
                   open(2) for reasons why this may be useful.

RETURN VALUE         top

       On success, these system calls return a new file descriptor.  On
       error, -1 is returned, and errno is set to indicate the error.

ERRORS         top

       EINVAL (inotify_init1()) An invalid value was specified in flags.

       EMFILE The user limit on the total number of inotify instances has
              been reached.

       EMFILE The per-process limit on the number of open file descriptors
              has been reached.

       ENFILE The system-wide limit on the total number of open files has
              been reached.

       ENOMEM Insufficient kernel memory is available.
