    The purpose of this article is to answer some questions related to safe port of C/C++ code on 64-bit systems. The article is written as an answer to the topic often discussed on forums and related to the use of /Wp64 key and Viva64 tool.

  • All about 64-bit programming in one place

    In this post I've collected a lot of links on the topic of 64-bit C/C++ software development. These include my articles and articles by my colleagues in the sphere of developing safe and efficient 64-bit code; FAQ's and a training course. There are also many reviews of third-party articles on 64-bit software development. Enjoy yourself studying the materials.

    Knowledge base of issues related to 64-bit and parallel software development

    The main method of promoting our program product PVS-Studio is to tell the developers about the type issues this tool can solve.

    Note. PVS-Studio is an add-in module for Visual Studio 2005/2008 (and 2010 soon) that allows you to detect a lot of various errors in 64-bit and parallel OpenMP applications. PVS-Studio is a contemporary interactive static C/C++ code analyzer. By 'interactive', for instance, we mean the capability of warning filtration and suppression without relaunching the analysis.

    This article is the most complete collection of examples of 64-bit errors in the C and C++ languages. The article is intended for Windows-application developers who use Visual C++, however, it will be useful for other programmers as well.

  • The reasons why 64-bit programs require more stack memory

    In forums, people often say that 64-bit versions of programs consume a larger amount of memory and stack. Saying so, they usually argue that the sizes of data have become twice larger. But this statement is unfounded since the size of most types (char, short, int, float) in the C/C++ language remains the same on 64-bit systems. Of course, for instance, the size of a pointer has increased but far not all the data in a program consist of pointers.
