inotify_init, inotify_init1 - initialize
an inotify instance
#include <sys/inotify.h>
int inotify_init(void);int inotify_init1(int flags);
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.
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; 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.
