sizeof( 2 ); // 2的类型为int,所以等价于 sizeof( int ); sizeof( 2 + 3.14 ); // 3.14的类型为double,2也会被提升成double类型,所以等价于 sizeof( double ); sizeof也可以对一个函数调用求值,其结果是函数返回类型的大小,函数并不会被调用,我们来看一个完整的例子: char foo() { printf("fo...
Developer --|> sys: 导入sys模块 Developer --|> Variable: 创建变量 Developer --|> sys.getsizeof(): 使用sys.getsizeof()函数 sys.getsizeof() --> Size: 获取变量大小 Size --|> Developer: 显示变量大小 以上关系图描述了开发者教导新手学习Python,并且在此过程中使用了sys模块和sys.getsizeof()...
1、什么是sizeof 首先看一下sizeof在msdn上的定义: The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type (including aggregate
The sizeof keyword gives the amount of storage, in bytes, associated with a variable or a type(including aggregate types). This keyword returns a value of type size_t. ——来自MSDN 其返回值类型为size_t,在头文件stddef.h中定义为:typedef unsigned int size_t; 从sizeof的定义可以看出:sizeof...

This patch first gets the base page size once and stores it into a static variable. Then, it checks if more data than 16 times the base page size is read, which in the case of a pipe would limit the read to exactly 16 times the base page size. If that is the case, a check is...
