INOTIFY_INIT(2) Linux Programmer's Manual INOTIFY_INIT(2)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.
