Struct inotify_sys::inotify_event [−][src]
#[repr(C)]pub struct inotify_event { pub wd: c_int, pub mask: uint32_t, pub cookie: uint32_t, pub len: uint32_t, }
Describes a file system event
From inotify(7):
To determine what events have occurred, an application read(2)s from the inotify file descriptor. If no events have so far occurred, then, assuming a blocking file descriptor, read(2) will block until at least one event occurs (unless interrupted by a signal, in which case the call fails with the error EINTR; see signal(7)).
Each successful read(2) returns a buffer containing one or more of this structure.
Fields
wd: c_int
Identifies the watch for which this event occurs
This is one of the watch descriptors returned by a previous call to
inotify_add_watch()
.
mask: uint32_t
Describes the type file system event
One of the following bits will be set, to identify the type of event:
IN_ACCESS
IN_ATTRIB
IN_CLOSE_NOWRITE
IN_CLOSE_WRITE
IN_CREATE
IN_DELETE
IN_DELETE_SELF
IN_IGNORED
IN_MODIFY
IN_MOVED_FROM
IN_MOVED_TO
IN_MOVE_SELF
IN_OPEN
IN_Q_OVERFLOW
IN_UNMOUNT
Some constants cover multiple bits, and can be used for a less precise check of the event type:
In addition, the IN_ISDIR
bit can be set.
A number that connects related events
Currently used only for rename events. A related pair of
IN_MOVED_FROM
and IN_MOVED_TO
events will have the same,
non-zero, cookie. For all other events, cookie is 0.
len: uint32_t
The length of name
Used to determine the size of this structure. When name
isn't present (name
is only present when an event occurs
for a file inside a watched directory), it is 0. When name
is present, it counts all of name
's bytes, including \0
.
The
name
field is present only when an event is returned for a file inside a watched directory; it identifies the file pathname relative to the watched directory. This pathname is null-terminated, and may include further null bytes ('\0') to align subsequent reads to a suitable address boundary.
The name
field has been ommited in this struct's definition.
