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.
inotify_init1()
was added in Linux 2.6.27.
