Microsoft C Runtime [ iPad ]

| Feature | Description | |---------|-------------| | | strcpy_s(dest, dest_size, src) prevents buffer overflows. | | Parameter validation | Invalid pointers or null args in CRT functions trigger invalid parameter handler. | | Heap hardening | malloc and free implement heap cookies, guard pages (in debug), free list validation. | | /GS (buffer security check) | Compiler-inserted stack cookies checked on function return; failure calls __report_gsfailure . | | Safe unlinking of DLLs | Prevents DLL preload attacks. | | _set_printf_count_output | Controls %n specifier behavior to prevent format string exploits. | | _controlfp_s | Secure version of FPU control word manipulation. |

Modern CRT consists of three logical parts: microsoft c runtime

The CRT is not a single file. Over the years, Microsoft has evolved its packaging, linking models, and security features in response to application deployment needs, performance demands, and the complexity of the Windows ecosystem. | Feature | Description | |---------|-------------| | |

The Microsoft C Runtime is typically deployed as a DLL (Dynamic Link Library) file, which is loaded into memory when a program that depends on it is executed. The C Runtime DLL is usually included with Microsoft Visual C++ installations and can be redistributed with applications. | | /GS (buffer security check) | Compiler-inserted

The Microsoft C Runtime (CRT) is essentially the "instruction manual" for how C and C++ programs communicate with the Windows operating system. If you have ever looked at your installed programs and wondered why you have twenty different versions of "Microsoft Visual C++ Redistributable," you are looking at the CRT. 1. What is the CRT?

AROS - a solid foundation

AROS is a complete NG OS based on AmigaOS 3.1 API. This means it includes many known components like datatypes (24bit), network stack, AHI, MUI-Implementation (Zune), USB-support, Themeing, window out of screen and RTG. The default desktop (Wanderer) is functional similar to old 3.1 workbench.

Additions

Addition there are Scalos and Magellan desktops. Both are highly configurable what I made extensive use of. Also Aros Vision is extended with additional commodities in WBStartup, handler and devices, libraries, commands in C and lots of software including many applictations, guis, games, demos.

Useable on both WinUAE and Apollo V4
