Detailed Description

Module for USB device notification.

Enumeration Type Documentation

Hot plug config flags.

Enumerator
KHOT_FLAG_NONE	No flags (or 0)
KHOT_FLAG_PLUG_ALL_ON_INIT	Notify all devices which match upon a succuessful call to HotK_Init.
KHOT_FLAG_PASS_DUPE_INSTANCE	Allow other KHOT_HANDLE instances to consume this match.
KHOT_FLAG_POST_USER_MESSAGE	If a `UserHwnd` is specified, use `PostMessage` instead of `SendMessage`.

KUSB_EXP BOOL KUSB_API HotK_Init	(	_out KHOT_HANDLE *	Handle,
		_ref PKHOT_PARAMS	InitParams
	)

Returns: On success, TRUE. Otherwise FALSE. Use GetLastError() to get extended error information.

KUSB_EXP BOOL KUSB_API HotK_Free ( _in KHOT_HANDLE Handle )

Frees the specified hot-plug handle.

Parameters

[in] Handle hot-plug handle pointer to free.

Returns: On success, TRUE. Otherwise FALSE. Use GetLastError() to get extended error information.
