Parameters

[in]	appRef	Ref to the app.
[in]	path	Absolute path to the device.
[in]	permissions	Permission string, "r", "w", "rw".

◆ le_appCtrl_AddTraceAttachHandler()

le_appCtrl_TraceAttachHandlerRef_t le_appCtrl_AddTraceAttachHandler	(	le_appCtrl_AppRef_t	appRef,
		le_appCtrl_TraceAttachHandlerFunc_t	attachToPidPtr,
		void *	contextPtr
	)

Parameters

[in] handlerRef

◆ le_appCtrl_TraceUnblock()

void le_appCtrl_TraceUnblock	(	le_appCtrl_AppRef_t	appRef,
		int32_t	pid
	)
