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.
