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 flagsis 0, then inotify_init1() is the same as inotify_init(). The following values can be bitwise ORed in flagsto obtain different behavior:

IN_NONBLOCK
Set the O_NONBLOCKfile 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_CLOEXECflag 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 errnois 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.
