  2. Scattering parameters - Wikipedia

    en.wikipedia.org/wiki/Scattering_parameters

    The Scattering transfer parameters or T-parameters of a 2-port network are expressed by the T-parameter matrix and are closely related to the corresponding S-parameter matrix. However, unlike S parameters, there is no simple physical means to measure the T parameters in a system, sometimes referred to as Youla waves.

  3. Variadic macro in the C preprocessor - Wikipedia

    en.wikipedia.org/wiki/Variadic_macro_in_the_C...

    Both the C99 and C++11 standards require at least one argument, but since C++20 this limitation has been lifted through the __VA_OPT__ functional macro. The __VA_OPT__ macro is replaced by its argument when arguments are present, and omitted otherwise. Common compilers also permit passing zero arguments before this addition, however.

  4. Variadic template - Wikipedia

    en.wikipedia.org/wiki/Variadic_template

    The variadic template feature of C++ was designed by Douglas Gregor and Jaakko Järvi [1] [2] and was later standardized in C++11. Prior to C++11, templates (classes and functions) could only take a fixed number of arguments, which had to be specified when a template was first declared.

  5. Type signature - Wikipedia

    en.wikipedia.org/wiki/Type_signature

    Manipulation of these parameters can be done by using the routines in the standard library header < stdarg. h >. In C++, the return type can also follow the parameter list, which is referred to as a trailing return type. The difference is only syntactic; in either case, the resulting signature is identical:

  6. x86 calling conventions - Wikipedia

    en.wikipedia.org/wiki/X86_calling_conventions

    The order in which atomic (scalar) parameters, or individual parts of a complex parameter, are allocated; How parameters are passed (pushed on the stack, placed in registers, or a mix of both) Which registers the called function must preserve for the caller (also known as: callee-saved registers or non-volatile registers)

  7. C++ Standard Library - Wikipedia

    en.wikipedia.org/wiki/C++_Standard_Library

    The C++ Standard Library is based upon conventions introduced by the Standard Template Library (STL), and has been influenced by research in generic programming and developers of the STL such as Alexander Stepanov and Meng Lee. [4] [5] Although the C++ Standard Library and the STL share many features, neither is a strict superset of the other.

  8. Calling convention - Wikipedia

    en.wikipedia.org/wiki/Calling_convention

    The order in which parameters are passed. Options include left-to-right order, or right-to-left, or something more complex. How functions that take a variable number of arguments (variadic functions) are handled. Options include just passed in order (presuming the first parameter is in an obvious position) or the variable parts in an array.

  9. Curiously recurring template pattern - Wikipedia

    en.wikipedia.org/wiki/Curiously_recurring...

    The use of CRTP can be simplified using the C++23 feature deducing this. [13] [14] For the function signature_dish to call a derived member function cook_signature_dish, ChefBase needs to be a templated type and CafeChef needs to inherit from ChefBase, passing its type as the template parameter.
