它在自己的作用域内给一个已经存在的类型一个别名,可是You cannot use the typedef specifier inside a function definition。 3)typedef int * int_ptr; 与 #define int_ptr int * 作用都是用int_ptr代表 int * ,可是二者不同,正如前面所说 ,#define在预处理 时进行简单的替换,而typedef不是简单替换 ,而...
typedefs defined inside a class are "part of the class", that is to say the typedef isn't visible/accessible outside the class functions unless you fully qualify it by class::typedefname Additionally the typedef is also public, protected or private depending so it's access is also restricte...
Specifically, C99 does not support typedef redeclarations, which is a C11 feature. // some_header.h typedef struct _zval_struct zval; void some_func(zval *zv); // zend_types.h struct _zval_struct { ... }; typedef struct _zval_struct zval; Some headers might want to forward declare ...

如何将以下C代码转换为Python,特别是部分: uint8_t number_of_items [MAX_NUMBER_OF_ITEMS] 我尝试这样做: class Sensor Info: status: int serial_number_of_items: List[int] version: int ,此外,我如何使用 struct.pack进行序列化? 创建一个类来封装 Items_Info_t并管理其序列化/避难所。
