API. XMLHttpRequest is a JavaScript Object used to execute asynchronous HTTP requests. Philip McCarthy describes a sequence diagram in his article (see figure 1). This diagram is helpful for understanding how XMLHttpRequest objects support Ajax design (see references, to obtain the link pointing to the full text ). Figure 1. Philip McCarthy's Ajax sequence diagram From this figure, you can clearly see how

interrupt is to be used, it is first to establish an interrupt descriptor, IDT, which functions as:In the Head.s file, IDT is established, for example, to use the int 0x80, starting from the _idt to find the place where the offset is 0x80 to execute the code.. align 3# aligns memory address boundaries in 8-byte fashion. _idt:.fill 256,8,0# IDT is uninitialized# 256 items, 8 bytes each, 0.

IOS development -- call between applications (2), ios development In the previous article, I explained how to call an app between my own applications. Today I will introduce how to call an app that comes with IOS. 1. Call the app

). Function order and function suffix are the beginning and end assembly code automatically added by the compiler. Their implementation is related to the CPU architecture and compiler. All operations except Step 5 represent function entities constitute function calls. The following describes the main Commands used to call a function. Push: The top pointer ESP of the stack is reduced by four bytes. Register data (four bytes, Less Than Zero) is pushed

One, Java side:Define the native method, ' public native long factorial (int n); ', the method is implemented in C + +, computes ' 1 to 20 factorial and ', the argument ' int n ' is the factorial of the first n and (here is 20). Returns the result of the calculation, and return to the Java call.The code is:1 Public classFactorialjava {2 3 Public native Long

implement two array mergesThe same push method does not provide an array of push, but it provides push (Param1,param,... paramn) So it is also possible to replace this array with apply, namely:? 1234 var arr1= new array ( " 1 " " 2 " , "3" ); var arr2= new array ( "4" , Code class= "JS string" > "5" "6" ); array.prototype.push.apply (ARR1,ARR2); console.log (arr1);

, the architecture used by the PC, the variation range of a non-negative integer is 0-32767, which is also the ID of all possible processes. In fact, from the process ID name, we can see that it is the ID number of the process, each person's ID number will not be the same, each process's ID will not be the same. One or more processes can be combined to form a process group, and one or more process groups can be combined to form a session ). In this way, we have the ability to perform batch opera

Underlying file access:Process: A running program that has a number of file descriptors associated with the value, and how many file descriptors depend on the configuration of the system.When a program starts running, three file descriptors are typically opened:0: Standard input1: Standard output2: Standard errorOther file descriptors can be associated with files and devices through system calls (open).Write system call:Function: Writes the first nbytes bytes of a buffer (BUF) to the file associ

If you have not performed the first experiment, please do it first. This experiment describes how to use the Atlas announcement block to call web services instead of writing JS scripts, we should remember that in our first experiment, we used JS scripts to call methods in Web Services. Now we should not write that JS script, I don't know why I directly use the Atlas announcement block to

project in VC ++ and name it cdecl. The Code is as follows: int _ cdecl add (int A, int B); // function declaration void main () {Add (1, 2 ); // function call} int _ cdecl add (int A, int B) // function implementation {return (a + B);} The disassembly code at function call is as follows :; add (
