SWIG C++ variable接口文件 Writed by tcy in Shanghai songjiang xiaokunshan.
Date:2020/10/2 2:00 used:You can put the tcy_variable.i in %module modulename next line. 说明：常量变量名称有后缀_SWIG的未在头文件中定义，无此后缀的变量在头文件中有声明；import modulename as obj; 类似obj.x11的值都可修改不建议采用。*///1.以下常量变量定义在头文件中，若想在python使用必须添加：//1.常量-直接访问
#define PI 3.14159 // python中访问：obj.PI 可修改值
#define VERSION "1.0" //2.只读变量：-用cvar访问const int NO1 = 1010; // python中访问：modulename.cvar.NO1不可修改
int const NO2 = 2020; %constant int NO1_SWIG = 3030; //【不建议】obj.NO1_SWIG
%constant int NO2_SWIG = 4030; //【不建议】%constant int x11=100 ; //【不建议】obj.x11可修改值< /FONT> //声明普通变量只读
%immutable; //【不建议】obj.x12可修改值
extern int x12; //【建议】 obj.cvar.x12不可修改值

extern int x13; // obj.cvar.x13不可修改值

extern int g_Totals_swig; //【不建议】用obj.cvar.g_Totals_swig 访问
