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
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; 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.
These system calls are Linux-specific.
