In C, i would keep using the macros. It's a myth that using the third method will slow down your program in any way. I just prefer the enumeration since the values you get are rvalues - you can't get their address, which i regard as an added safety. In addition, there is much...
[Chapter 7] 7.2 Defining MacrosBryan Costales &Eric Allman
C macros offer a convenient way to insert assembly code into your source code, but they demand extra care because a macro expands into a single logical line. To create trouble-free macros, follow these rules:Enclose the __asm block in braces. Put the __asm keyword in front of each ...
I have some macros in my text editor that make this easy. They generate a standard header for me which I fill in. The header looks something like the examples below. Example 1: A message which has simple parameters, and which is sent but whose response doesn't matter: /*** * UWM...
New macros: * ``PyCFunction_GET_CLASS`` New types: The following will be added to Python C-API: * ``PyCMethodObject`` * ``PyType_FromModuleAndSpec`` function * ``PyType_GetModule`` function * ``PyType_GetModuleState`` function * ``METH_METHOD`` call flag * ``PyCMethod`` function...
C 巨集提供便利的方式,可將組譯程式碼插入原始程式碼中,但是,因為巨集會展開成單一邏輯程式敘述行,所以必須特別小心。 為了使建立的巨集不會發生任何錯誤,請遵循這些規則: 使用大括號將__asm區塊括住。 將__asm關鍵字放在每個組譯碼指令前面。 使用舊式的 C 註解 (/* comment */) 而不是組譯碼樣式的註解 ...
0 to 100 g/d (although tolerance of more than 70 g/d when consuming adequate protein is uncommon). Note: due to wide variations in total energy intakes in the various phases of nutritional ketosis, specifying carbohydrate as a percent of daily intake (aka ‘macros’) is of marginal ...
