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