INOTIFY_INIT(2) Linux Programmer's Manual INOTIFY_INIT(2)
inotify_init, inotify_init1 - initialize an inotify instance
#include <sys/inotify.h>
int inotify_init(void);
int inotify_init1(int flags);
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.
On success, these system calls return a new file descriptor. On error, -1 is
returned, and errno is set to indicate the error.
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.
inotify_init() first appeared in Linux 2.6.13. inotify_init1() was added in
Linux 2.6.27.
These system calls are Linux-specific.
