摘要： The NGen.exe tool that ships with the .NET Framework can be used to compile IL code tonative code when an application is installed on a user’s machine. Since the code is compiledat install time, the CLR’s JIT compiler does not have to compile the IL code at runtime, andthis can improve the applicat. 阅读全文

摘要： Boost is a community and web site for the development of free, open source, peer-reviewed C++ libraries. Boost plays an influential role in C++ standardization. Boost offers implementations of many TR1 components, but it also offers many other libraries, too. 阅读全文

摘要： The primary standard C++ library functionality consists of the STL, iostreams, and locales. The C99 standard library is also included. TR1 adds support for smart pointers (e.g., tr1::shared_ptr), generalized function pointers (tr1::function), hash-based containers, regular expressions, and 10 other. 阅读全文

摘要： Take compiler warnings seriously, and strive to compile warning-free at the maximum warning level supported by your compilers. Don't become dependent on compiler warnings, because different compilers warn about different things. Porting to a new compiler may eliminate warning messages you've 阅读全文

摘要： When you write a placement version of operator new, be sure to write the corresponding placement version of operator delete. If you don't, your program may experience subtle, intermittent memory leaks. When you declare placement versions of new and delete, be sure not to unintentionally hide the 阅读全文

摘要： operator new should contain an infinite loop trying to allocate memory, should call the new-handler if it can't satisfy a memory request, and should handle requests for zero bytes. Class-specific versions should handle requests for larger blocks than expected. operator delete should do nothing i 阅读全文

摘要： There are many valid reasons for writing custom versions of new and delete, including improving performance, debugging heap usage errors, and collecting heap usage information. 阅读全文

摘要： set_new_handler allows you to specify a function to be called when memory allocation requests cannot be satisfied. Nothrow new is of limited utility, because it applies only to memory allocation; subsequent constructor calls may still throw exceptions.1#include<iostream>2usingnamespacestd;34cl 阅读全文
