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.
