The C++ standard consists of the core language and the C++ Standard library. C++ supports static and dynamic memory allocation.
Borland c 64bit software#
Its application includes device drivers, application programs, embedded software, systems software and video games. C++ is widely used for both hardware and software level programming. C++ was originally named C with classes because it provided the Object Oriented Programming Language features. It was developed by Bjarne Stroustrup in 1979 at Bell labs.

See Debugging C++Builder 64-Bit Windows Applications.Turbo C++ is a one of the most powerful and popular Object Oriented Programming Language used these days. That is, the Final output directory should be different for Win32 and Win64.
If you override the Package output directory, you can verify that the Final output directory is correctly set on Project > Options > C++ (Shared Options). If you previously set the Package output directory to produce a Win32 package, make sure to change the path for your Win64 project on the Tools > Options > Environment Options > C++ Options > Paths and Directories (C++) page, so that your Win32 package is not overwritten.For exporting a component class from a package, you must ensure at least one non-inline member for each component (this is done for you by the File > New Component wizard).This requirement applies to variables, functions and classes that are meant to be exposed to consumers of the package.Ĭlass PACKAGE TTest : public System :: TObject PACKAGE bool GoodieFlag PACKAGE void _fastcall SuperFunc ( const System :: UnicodeString S ) įor general information, see Building Packages. You must use PACKAGE for both Win32 and Win64, but Win64 exports only if there is a definition present.
Borland c 64bit code#
If no definition is seen, the compiler will treat the code element as imported. For classes, if one non member is defined, the class is exported. For these platforms, static libraries can be used.ĭifferences between Win32 and Win64 packagesįor Win64, the compiler exports code elements marked as PACKAGE if they are defined in the current translation unit.

Note that C++Builder does not produce dylibs for the Mac, or packages for the iOS and Android platforms. You can also do static linking to a 64-bit Windows package, and you can consume packages using C++Builder 64-bit Windows. bpl files), beginning in the XE6 release. Producing 64-bit Packages Is Now SupportedīCC64 produces 64-bit Windows packages (. With BCC32, including windows.h is not required, but BCC64 requires windows.h and as any other Clang-enhanced C++ compiler it is more strict about #includes. _WIN64 is defined only for Win64 targets because _WIN32 is also defined, check _WIN64 first, something like this: This allows programs to target (modern) Windows in general, among other platforms.
_WIN32 is defined (as the integer 1) for both Win32 and Win64 targets. Win64 is an "LLP64" data model: long long and pointers are 64-bit, while int (and long) are still 32-bit. You could use unsigned int in place of size_t, although it is not portable. In Win32's "ILP32" data model, int (and long) and pointers are 32-bit. In contrast, in the segmented Large memory model of DOS, pointers were 32-bit, while the largest object was 64KB. (These modern Windows memory models are flat. In Win32 and Win64, this is the same size as a pointer. Size_t is defined as an unsigned integral type, passed to malloc and the result of sizeof, with enough bits to represent the size of the largest possible object in the memory/data model. 64-bit Windows Data Types Compared to 32-bit Windows Data Types.Moving to 64-bit development is a widely covered topic on the Internet, especially as it relates to C++ and Windows.įor more information, see the following topics: 2.2.1 Differences between Win32 and Win64 packagesĭifferences Between 32-bit Windows and 64-bit Windows Applications.
