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 open file description (see
open(2))
referred to by the new file descriptor.
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.
