restrict

问题 I'm in the process of updating performance critical libraries to use restrict, as implemented in C++11 by g++ and MSVC with the keyword __restrict . This seems to be the most-standard-extension, so I'll use restrict and __restrict interchangeably. restrict is a C99 keyword, but nevertheless compilers have defined important uses for it in C++. This post intends to be a "question" asking about what each C++-specific use is and what it means, followed by a CW answer answering it. Feel free to

问题 Suppose we have a function declaration for which we do not have access to its definition: void f(int * restrict p, int * restrict q, int * restrict r); Since we do not know how the pointers will be accessed, we cannot know if a call will trigger undefined behavior or not -- even if we are passing the same pointer, like the example at 6.7.3.1.10 explains: The function parameter declarations: void h(int n, int * restrict p, int * restrict q, int * restrict r) { int i; for (i = 0; i < n; i++) p

问题 i am trying develop a code to restrict TextBox using C# to only allow numbers entry + comma(",") or dot(".") + only 2 numbers after dot or comma So this way see possible numbers that can entry: 3213,04 = OK 3211,664 = Not 32.31 = OK 32.3214 = Not 334,,00 = Not 3247,.00 = Not 214.,00 = Not 32.. = Not 8465,0 = Ok 654.0 = Ok Understood My goal ? I developed code bellow private void txtValormetrocubico_KeyPress(object sender, KeyPressEventArgs e) { if (txtValormetrocubico.TextLength >= 0 && (e

问题 I have GITOLITE on my server and I want to configure access to my repository. I want to restrict access to some branches for some users. I try a lot of variants how to configure gitolite.conf file and I didn't find solution how to restrict acces to some branches. 1) @developers1 = user1 @developers2 = user2 repo dbatest RW+ = @developers1 R test = @developers2 - test = @developers2 RW+ = @developers2 When user2 executed command: git push origin test : push succeed In gitolite log I had this

问题 I have two different libraries which refereed the base library called base.dll. One library using for web platforms another one using for windows platform (WPF). I have to restrict restrict one public property in WPF platform but I want to access it in web platform. How can achieve this? I am trying condition compilation but I don’t know how to do exactly. Please help me For Ex:- Base library: public Class CommonClass{ public string CssClass { get; set; } } Referenced Library 1 (Web) –

问题 I'm in the process of updating performance critical libraries to use restrict , as implemented in C++11 by g++ and MSVC with the keyword __restrict . There are a lot of routines and functions that look something like: void f(float a[],float b[]); In the above example, f is a routine whose arguments should be restricted. Unfortunately, as far as I can tell, this is impossible while maintaining that syntax. Now, clearly this can be rewritten using pointers as: void f(float*__restrict a,float*_

问题 I have a peculiar requirement where I need ensure that only a particular method from one class is allowed to call a public (non-static) method from a second class. Inheritance cannot be used. One option is to use StackTrace as follows: ClassA.java package org.rnd.stack; public class ClassA { public void methodA() throws IllegalAccessException { Exception fake = new Exception("FAKE-IGNORE"); StackTraceElement[] stack = fake.getStackTrace(); StackTraceElement st = stack[1]; if ("org.rnd.stack

问题 Since strict aliasing may help compiler optimize better, C99 introduced the restrict keyword which can be used as a qualifier of a variable if programmers guarantee that it won't be accessed through a pointer to a different type. However, typecasting between different types is inevitable for several reasons and this will make compiler assume that one pointer is not an alias of the other. Therefore, the workaround method is to disable the global strict aliasing optimization by passing -fno

问题 I want to add validation in javafx TextField such that user should only be able to insert integer values ([0-9] and Dot ). Also user should be able to insert either B or b(for Billion) and K or k (for Thousand) and M or m( for Million). Basically it should be an amountfield. Delete and Backspace should also work. for example : 10k should become 10,000.00 as soon as user hit k and K should not be displayed on amountfield (textfield) Similarly 10M or 10m should convert into 10,000,000.00

问题 This question isn't limited to people who know AppleScript, if you do Cocoa, etc., you should know the answer to this: I'm making a droplet in AppleScript that compresses JavaScript files, so obviously, I only want JavaScript files to be allowed into the scripts. Any ideas? Thanks so much. 回答1: property kJavascriptExtension : "js" property pValidFileList : {} on open of theFiles -- Executed when files are dropped on the script set fileCount to (get count of items in theFiles) repeat with
