C语言中构造类型一共有4种，它们分别是数组、结构体（struct）、共用体（union）、枚举类型（enum）。C语言中基本类型和枚举类型，统称算术类型（arithmetic type）。算术类型和指针类型，统称为标量类型（scalar type）。数组类型和结构类型被统称为聚合类型（aggregate type）。联合类型（union type）不被...

内存管理 assign:纯量类型(scalar type)的简单赋值操作 strong:拥有关系保留新值,释放旧值,再设置新值 weak:非拥有关系(nonowning relationship),属性所指的对象遭到摧毁时,属性也会清空 unsafe_unretained :类似assign,适用于对象类型,非拥有关系,属性所指的对象遭到摧毁时,属性不会清空。 copy:不保留新值,而是将其...
Any scalar value may receive a symbolic value either in a relative namespace like hp: Color.Green, or an absolute namespace like hp: MyGame.Example.Color.Green, but not hp: Green (since hp in the monster example schema) is not an enum type with a Green value). A namespace is relativ...
计算类API,包括标量计算API、向量计算API、矩阵计算API,分别实现调用Scalar计算单元、Vector计算单元、Cube计算单元执行计算的功能。 数据搬运API,上述计算API基于Local Memory数据进行计算,所以数据需要先从Global Memory搬运至Local Memory,再使用计算接口完成计算,最后从Local Memory搬出至Global Memory。执行搬运过程的接口...

However, pointers to scalar types are allowed. With Pro*C, declare pointers to char[n] and varchar[n] variables as pointers to CHAR or VARCHAR (with no length specification). Action: Correct or remove the declaration. PCC-00122 Input file name and output file name are identical Cause: ...
struct foo { int a; int b; }; struct foo *f; int *p; void main() { f = (struct foo *)p; /* struct pointer cast of scalar pointer error */ }5.3.2 空指针向结构指针的强制类型转换在以下示例中,空指针 vp 强制转换为结构指针。如果 lint -Xalias_level=weak(或更高),这将生成警告。
