python中所有的对象都实现了这两个属性refcnt与type,换句话说,实现了这两个成员的struct变量都是python中的对象。代码如下: typedef struct _object{ int ob_refcnt; //引用计数 struct _typeobject *ob_type; // 类型对象 }PyObject; 1. 2. 3. 4. 而之前提到的整数类型PyIntObject实现如下: typedef struct...

The PlayFab Party library uses several typedefs for convenient declarations of arrays of core types. It also provides typedefs for a few basic types to add semantic meaning and aid in static analysis. Macros are provided for dealing with PartyError return codes....
Negative values (other than -1 or PP_OK_COMPLETE) indicate error and are specified in pp_errors.h. Positive values for result usually indicate success and have some operation-dependent meaning (such as bytes read). Definition at line 34 of file pp_completion_callback.h. typedef struct PP...
However, in C99 this code is actually illegal if both of these headers end up being included, because redeclarations of typedefs are not allowed. To fix it, the typedef must be removed and the signatures must refer to the struct directly. // some_header.h struct _zval_struct; void some...
