type ArbitraryType int // Pointer represents a pointer to an arbitrary type. There are four special operations // available for type Pointer that are not available for other types: // - A pointer value of any type can be converted to a Pointer. // - A Pointer can be converted to a p...
C99标准中uintptr_t和size_t类型的区别:uintptr_t是可以容纳指针大小的integer type,但是size_t不一定是,在一些具有分段寻址机制的平台,size_t可能比一个指针的大小还小。 一、C99标准中uintptr_t和size_t类型的区别 uintptr_t是可以容纳指针大小的integer type,但是size_t不一定是,在一些具有分段寻址机制的平...

The UIntPtr type is designed to be an integer whose size is the same as a pointer. That is, an instance of this type is expected to be 32-bits in a 32-bit process and 64-bits in a 64-bit process.The UIntPtr type can be used by languages that support pointers, and as a common...
typeuintptruintptr 在64位平台上,底层的数据类型是: typedefunsignedlonglongintuint64;typedefuint64 uintptr; uintptr的用处也很大: uintptr可以和unsafe.Pointer类型互转(上面提到过)。 uintptr可以做指针运算,这一点有时候很重要,但是依赖平台,同一类型变量在不同的平台占用的存储空间大小不一样,在用uintptr做...
type uintptr uintptr 1. 2. 3. uintptr 是 Go 内置类型,表示无符号整数,可存储一个完整的地址。常用于指针运算,只需将 unsafe.Pointer 类型转换成 uintptr 类型,做完加减法后,转换成 unsafe.Pointer,通过 * 操作,取值或者修改值都可以。 下面是一个通过指针偏移修改结构体成员的例子,演示下 uintptr 的用法...
type uintptr uintptr uintptr是golang的内置类型,是能存储指针的整型,在64位平台上底层的数据类型是, 代码语言:javascript 复制 typedef unsigned long long int uint64; typedef uint64 uintptr; 一个unsafe.Pointer指针也可以被转化为uintptr类型,然后保存到指针型数值变量中(注:这只是和当前指针相同的一个数字...
