Many of these aspects can be controlled by just one compiler directive. For example, all WIN32 APIs are defined using the WINAPI preprocessor symbol. This symbol maps to _stdcall directive with the Microsoft compiler on the Intel platform. 1 summarizes the implication of this directive. 1. com to register it. Thanks. Argument-passing order Right to left Argument-passing convention By value, unless a pointer or reference type is passed Stack-maintenance responsibility Called function pops its own arguments from the stack Case-translation convention None Let’s look at how the compiler uses the definition of a class in generating machine language code.
By changing the private specifications, we still honor the basic rule of C++ encapsulation: Thou shall not change the public specifications of a C++ class. Then why did our TV simulation program break? The reason is that, the encapsulation mechanism that C++ supports is semantic (in terms of public and private members) and not binary. To understand this distinction, let’s examine how the compiler produced the object code for our TV program. When the TV code was compiled, the compiler used two pieces of information from the CVcr class definition: 1.
Stack-maintenance responsibility is uniform: The responsibility of cleaning the stack, that is, popping the arguments from the stack, can be conditionally specified for the called function or the calling function. Case-translation convention: The linker can be forced to resolve symbolic references as case-sensitive or case-insensitive. No name mangling for C-Style functions: By declaring a C-Style function as extern "C", the compiler’s name-mangling mechanism for the specific function can be turned off.
