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
       behavior:

       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.

       ENFILE The system limit on the total number of file descriptors has
              been reached.

       ENOMEM Insufficient kernel memory is available.

VERSIONS         top
