inotify_init, inotify_init1 - initialize an inotify instance
Standard C library (libc
, -lc
)
#include <sys/inotify.h>
int inotify_init(void);
int inotify_init1(int flags);
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:
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.
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.
On success, these system calls return a new file descriptor. On
error, -1 is returned, and errno
is set to indicate the
error.
(inotify_init1()) An invalid value was specified in
flags
.
The user limit on the total number of inotify instances has been reached.
The per-process limit on the number of open file descriptors has been reached.
The system-wide limit on the total number of open files has been reached.
