...在C语言宏中称为Variadic Macro,即变参宏。C99编译器标准允许定义可变参数宏(Macros with a Variable Number of Arguments),这样就可以使用拥有可变参数表的宏。 可变参数宏的一般形式为: #define DBGMSG(format, ...) fprintf (stderr, format, __VA_ARGS__) 省略号代表一个可以变化的参数表,变参必须...

and the one just before the ellipses is always an int which will represent the total number variable arguments passed. To get such a functionality, you need to use the stdarg.h header file which provides the functions and macros to implement the functionality of variable arguments....

因此,例如,如果 Objective-C API 接受 NSDictionary ,且其記載為採用磁碟區值從 0.0 到 1.0 的 索引鍵NSNumberXyzVolumeKey,以及XyzCaptionKey採用字串的 ,則您希望您的使用者擁有如下所示的好 API:C# 複製 public class XyzOptions { public nfloat? Volume { get; set; } public string Caption...
If C function arguments length is fixed,nfixedargsmust be null, or be the number of fixed arguments. Primitive types are representated by short string literals according tolibffi's type definition, I added more C friendly ones, seeprimitiveTypesinquickjs-ffi.jsfor details.Note:All C pointers ...
