NAME

       inotify_init, inotify_init1 - initialize an inotify instance

SYNOPSIS

       #include <sys/inotify.h>

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

DESCRIPTION

       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.

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