??Sun Guangdong 2015.5.25Reprint please indicate the source barThis is the second blog post in the Il2cpp Internals series. In this article, we will explore the C + + code generated by Il2cpp.exe. Along the way, we'll see how the managed types are represented in native code, and see how the run-time check is used to support. NET virtual machines, see how to loop Build more!We will encounter some very version-specific code, and a later version of unity

Valid tive c ++ Item 28 do not return handles or internalshandles that point to the internal data (internals) of the object. Suppose you are operating on a Rectangle class. Each rectangle can be represented by a vertex in the upper left corner and a vertex in the lower right corner. To ensure that a Rectangle object is as small as possible, you may decide not to store the vertex defining the rectangular range in the Rectangle class, but to put it into

relationship between length and capacity. The zero value of a slice isnil.lenAndcapFunctions will both return 0 for a nil slice. A slice can also be formed by "slicing" an existing slice or array. Slicing is done by specifying a half-open range with two indices separated by a colon. For example, the expressionb[1:4]Creates a slice including elements 1 through 3b(The indices of the resulting slice will be 0 through 2 ). b := []byte{‘g‘, ‘o‘, ‘l‘, ‘a‘, ‘n‘, ‘g‘}// b[1:4] == []byte{‘o‘, ‘l‘, ‘a‘},

All Parts:part 1 | Part 2 | Part 3 | Part 4 | Part 5The bootstrapping process is the key to understanding how the Go runtime works. Learning it is essential, if you want to move forward with Go. So the fifth installment in our Golang Internals series are dedicated to the Go runtime and, specifically, the Go bootstrap Process. This time you'll learn about: Go bootst

1. Since Windows NT, all versions of Windows are built entirely in Unicode, and when invoking a Windows function, if an ANSI string is passed to it, the function first converts the string to Unicode and then passes the result to the operating system. If you want the function to return an ANSI string, the operating system will first convert the Unicode string to an ANSI string and return the result to our application. Therefore, the system generates time and memory overhead.2. All COM interface m

be bound to an interrupted resource. This is possible in eka1. Now, only one ISR (interrupt service routines) is bound to an interrupt ). 2. To ensure a limited number of context conversions, we must limit a thread to a maximum of eight blocks. In eka1, this number is not limited. (Block is a basic object for memory allocation in Symbian OS-Chapter 7 memory model will show more details about this .) It is very important that not all eka2 services are restricted to real-time conditions. For ex

schedulers will be affected.SQL Server creates some hidden schedulers for processing these types of operations. In this way, when SQL Server performs these operations, the operating system can coordinate among multiple processors, thus avoiding blocks of individual UMS schedulers.Dbcc sqlperf (umsstats)Unpublished commands are used to view information about UMS schedulers, including the total number of users of related schedulers, the number of workers in the workers list, and so on.ReferenceIn

Two weeks ago, I bought an English version of Windows internals 6th edition. Although the fourth edition has translated Chinese from Pan aimin, The wdk version is different and the sixth edition has just arrived, the people's post and telecommunications Publishing House directly obtained the copyright of the Chinese version. After reading about two weeks, the progress was not fast, so I saw about 120 pages. I installed Windows 7, wdk, and some develo
