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.

CONFORMING TO

These system calls are Linux-specific.
