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_NONBLOCKSet 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_CLOEXECSet 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.
(inotify_init1()) An
invalid value was specified in flags.
The user limit on the total number of inotify instances has been reached.
The per-process limit on the number of open file descriptors has been reached.
The system-wide limit on the total number of open files has been reached.
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.
