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

       inotify_init, inotify_init1 - initialize an inotify instance

       #include <sys/inotify.h>

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

       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.

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

       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.

       inotify_init() first appeared in Linux 2.6.13.  inotify_init1() was added in Linux 2.6.27.

       These system calls are Linux-specific.
