Struct inotify::ffi::inotify_event

#[repr(C)]
pub struct inotify_event {
    pub wd: c_int,
    pub mask: uint32_t,
    pub cookie: uint32_t,
    pub len: uint32_t,
}

Describes an event.

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.

It is one of the watch descriptors returned by a previous call to inotify_add_watch().

mask: uint32_t

Contains bits that describe the event that occurred.

cookie: uint32_t

A unique integer 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 must be ommited in this definition.
