Windows命名风格

参考《2010.Windows内核原理与实现.潘爱民》2.3.2WRK源代码说明，

函数

内核

注：LPC只局限与一个机器的跨进程调用。RPC（Remote Procedure Call）分狭义和广义，狭义仅指跨机器的函数调用，广义当然包括把RPC相同的机制也用到了本地上，比如之前学习的D-BUS就虽然只在一个机器上运作，但也自称RPC，来源wikipedia: D-Bus，

In computing, D-Bus (short for "Desktop Bus"[4]) is a software bus, inter-process communication (IPC), and remote procedure call (RPC) mechanism that allows communication between multiple processes running concurrently on the same machine.[5][6]

注意下面的最后一句话，已画下划线强调，

D-Bus was conceived as a generic, high-level inter-process communication system. To accomplish such goals, D-Bus communications are based on the exchange of messages between processes instead of "raw bytes".[5][16] D-Bus messages are high-level discrete items that a process can send through the bus to another connected process. Messages have a well-defined structure (even the types of the data carried in their payload are defined), allowing the bus to validate them and to reject any ill-formed message. In this regard, D-Bus is closer to an RPC mechanism than to a classic IPC mechanism, with its own type definition system and its own marshaling.[5]

变量

srv03rtm/printscan/print/spooler/localspl/init.c有诸多sz开头的字符串

参考注册表支持的变量类型，

REG_SZ：A null-terminated string. This will be either a Unicode or an ANSI string, depending on whether you use the Unicode or ANSI functions

所以sz大概是String Zero。

类型

字符串

下述简称的互斥、联合关系：[N/L][P][C][W/T](CH/STR)

注：参考的之前添加到浏览器收藏夹learning.kernel.windows.CSDN：字符串类型（加入到本md后，这个收藏链接便可删掉了）

在32位系统中 N和L已经没有作用，只是为了向前兼容（兼容16位机器）才保留这些定义。

注：16位系统即现在x86中的实模式，该系统/模式下的唯一寻址方式是segment << 4 + offset。关于16位系统/实模式寻址，参考What are the segment and offset in real mode memory addressing?和回答指向的一篇文章Real-Mode Memory Management。
