0x02 变量的初始化 变量初始化(initialization),就是在定义变量的同时给变量设置一个初始值,我们称为 "赋初值"。 数据类型 变量名 = 初始值; 1. 建议在定义变量时给变量设置初始值,虽然不赋值也是允许的,但是我们不建议这么做! int a = 0; // 设置初始值 int b; // 不推荐 1. 2. 比如我们定义整型...

Restore the thread state from the local variable. 具体到实际代码如下: PyThreadState*_save;_save=PyEval_SaveThread();#该接口返回线程状态并释放GIL...DosomeblockingI/Ooperation...PyEval_RestoreThread(_save); 从这里可以看出,全局解释器锁是用来保护一个全局变量,该全局变量指向线程的状态数据。

例如: a_local_variable, a_struct_data_member, a_class_data_member_. 通用变量名 std::string table_name; // OK - lowercase with underscore. std::string tableName; // Bad - mixed case. 类数据成员名 类的数据成员,无论是静态的还是非静态的,都像普通的非成员变量一样命名,但后面带有下划线。
Disable local variable initialization. This is the default. %all Turn on all these runtime checking features. %none Disable all these runtime checking features. Stack overflows, especially in multithreaded applications with large arrays allocated on the stack, can cause silent data corruption ...
