NAME
       inotify_init, inotify_init1 - initialize an inotify instance

SYNOPSIS
       #include <sys/inotify.h>

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

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

ERRORS
       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.

VERSIONS
       inotify_init() first appeared in	 Linux	2.6.13;	 library  support  was
       added  to  glibc	 in  version  2.4.  inotify_init1() was added in Linux
       2.6.27; library support was added to glibc in version 2.9.

CONFORMING TO
       These system calls are Linux-specific.
