如果微筛选器提供具有非NULLContextAllocateCallback成员的FLT_CONTEXT_REGISTRATION结构,则它无法为该上下文类型提供任何其他FLT_CONTEXT_REGISTRATION结构。 如果微型筛选器提供两个或更多相同的FLT_CONTEXT_REGISTRATION结构,则只会使用第一个结构。 其他人将被忽略。
若要指定此例程,微筛选器驱动程序会将指向该例程的指针存储在上下文类型的FLT_CONTEXT_REGISTRATION结构的 ContextFreeCallback 成员中。有关上下文注册的详细信息,请参阅 FLT_CONTEXT_REGISTRATION的参考条目。要求展开表 要求值 目标平台 桌面 标头 fltkernel.h (包括 Fltkernel.h) IRQL <=APC_LEVEL...
ContextRegistration FLT_CONTEXT_REGISTRATION结构的可变长度数组,适用于微筛选器使用的每个上下文类型。 数组中的最后一个元素必须是 {FLT_CONTEXT_END}。 此成员是可选的,可以为NULL。 OperationRegistration 一个由FLT_OPERATION_REGISTRATION结构的可变长度数组,每种类型的 I/O 各有一个,微筛选器为其注册预操作...

I tried checking forcontext.mountedbefore calling thegoBack()method. But the error keeps happening. [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: This widget has been unmounted, so the State no longer has a context (and should be considered defunct). Consider canceling...

In this context, molecular imaging techniques such as positron emission tomography (PET) imaging have been advocated for therapy response evaluation. 18F-fluorodeoxyglucose (18F-FDG) is used to assess tumor glycolytic metabolism, and is the most commonly used PET tracer. Previous studies have shown ...
