// Type of the `on_crash` callback.
//
// The `on_crash` callback replaces the `before_send` callback for crash events.
// The interface is analogous to `before_send` in that the callback takes
// ownership of the `event`, and should usually return that same event. In case
// the event should be discarded, the callback needs to call
// `sentry_value_decref` on the provided event, and return a
// `sentry_value_new_null()` instead.
//
// Only the `inproc` backend currently fills the passed-in event with useful
// data and processes any modifications to the return value. Since both
// `breakpad` and `crashpad` use minidumps to capture the crash state, the
// passed-in event is empty when using these backends, and they ignore any
// changes to the return value.
//
// If you set this callback in the options, it prevents a concurrently enabled
// `before_send` callback from being invoked in the crash case. This allows for
// better differentiation between crashes and other events and gradual migration
// from existing `before_send` implementations:
//
//  - if you have a `before_send` implementation and do not define an `on_crash`
//    callback your application will receive both normal and crash events as
//    before
//  - if you have a `before_send` implementation but only want to handle normal
//    events with it, then you can define an `on_crash` callback that returns
//    the passed-in event and does nothing else
//  - if you are not interested in normal events, but only want to act on
//    crashes (within the limits mentioned below), then only define an
//    `on_crash` callback with the option to filter (on all backends) or enrich
//    (only inproc) the crash event
//
// This function may be invoked inside of a signal handler and must be safe for
// that purpose, see https://man7.org/linux/man-pages/man7/signal-safety.7.html.
// On Windows, it may be called from inside of a `UnhandledExceptionFilter`, see
// the documentation on SEH (structured exception handling) for more information

//
// Platform-specific behavior:
//
//  - does not work with crashpad on macOS.
//  - for breakpad on Linux the `uctx` parameter is always NULL.
//  - on Windows the crashpad backend can capture fast-fail crashes which
// by-pass SEH. Since `on_crash` is called by a local exception-handler, it will
// not be invoked when such a crash happened, even though a minidump will be
// sent.
