This pointer must be an absolute directory path, so you may need to tweak this value in your own code.
这个指针必须是一个绝对目录路径，因此您可能需要在自己的代码中调整该值。
Methods can actually be declared on both value and pointer types.
方法实际上既可以声明为值也可以声明为指针类型。
That means a reference type can have a null pointer, but a value type cannot have a null value.
这意味着引用类型可能有空指针，但是数值类型不能有空值。
The POSIX 1003.1 standard defines strerror_r , which accepts a pointer to a buffer and a buffer size in addition to the error value.
POSIX 1003.1标准定义strerror _ r，该函数除接受错误值之外，还接受缓冲区中的指针和缓冲区大小。
Binary trees are represented by nodes that have a data value and a left and right pointer; however, there are many data structures that require trees with more than just a left and right branch.
描述二叉树(binarytree)的节点有一个数据值、一个左指针和一个右指针；不过，很多数据体要求树不只有一个左分支和一个右分支。
You can simulate this yourself by using a printf call and the strerror function, which returns a pointer to the textual representation of the current errno value.
您可以通过使用printf调用和strerror函数(该函数返回当前errno值的文字表示形式的指针)来模拟此程序。
This function returns a pointer to the value in the environment or NULL if there is no match.
这个函数会返回一个 指向环境中的值的指针，或者如果不匹配则返回 NULL。
When you take the mouse pointer on top of the pie chart pointing to each database portion, you can see the percentage value that particular space has covered within the pie chart.
如果把鼠标指针放在饼图上面，指向每个数据库部分，就会看到对应的百分数。
Values of this type can now be allocated using the built-in function new, which returns a pointer to the value in memory with all slots initialized to the zero value.
现在这一类型的值可以通过内建的函数new来分配，这将返回一个指针，指向一块内存单元，其所占内存槽初始化为零。
Write code to change the value of a pointer. Write code to change the value to which the pointer points.
编写代码修改指针的值；然后再编写代码修改指针所指对象的值。
When first using Pointers, the difference in whether an assignment is to the pointer or through the pointer to the value pointed to can be confusing.
对于初学指针者，给指针赋值和通过指针进行赋值这两种操作的差别确实让人费解。
A pointer to the converted value.
一个指针指向转换后的值。
The data pointer value is not valid.
数据指针值无效。
In an unsafe context, a type may be a pointer type as well as a value type or a reference type.
在不安全的上下文中，类型可以是指针类型以及值类型或引用类型。
When we pass an array, the argument is a pointer to the first element in the array. That pointer value is copied; the array elements themselves are not copied.
而在传递数组时，实参是指向数组第一个元素的指针，形参复制的是这个指针的值，而不是数组元素本身。
This specifies the system call's offset value, which is passed as an integer pointer.
指定系统调用的偏移值，以一个整数的指针进行传递。
Because the runtime allocates memory for an object by adding a value to a pointer, it is almost as fast as allocating memory from the stack.
由于运行时通过为指针添加值来为对象分配内存，所以这几乎和从堆栈中分配内存一样快。
The object reference is popped from the stack and unboxed to a value type pointer.
从堆栈中弹出对象引用并取消装箱为值类型指针。
The value type pointer is pushed onto the stack.
将值类型指针推送到堆栈上。
If you have a pointer to a structure and the value of the pointer is correct, every member variable of the structure will show the correct value.
如果您有指向结构的指针而且指针的值是正确的，那么结构的每个成员变量都将显示正确值。
The value at the location pointed to by the pointer is not necessarily valid.
位于指针指向的位置的值并不是一定有效的。
Normally, this is solved by each entry in the hash table being a pointer to a linked list, and the linked list would hold all the entries that hash to that same value.
通常的解决办法是为每一个哈希值指向一个链表，用于存放所有哈希冲突的值；
You probably want to increment the integer value, not the pointer.
你可能想增加整数值，而不是指针。
This is because the compiler has to preserve the value of the null pointer through all conversions.
使用引用作为函数的参数可能比使用指针更有效率。
Structures are value types and classes are reference types - classes always provide at least one level of memory indirection (a pointer to a value).
结构是值类型，类是引用类型-类始终提供至少一级内存间接寻址(指向某一值的指针)。
It can be treated as a scalar value or a pointer to a structure containing multiple parameters, or it can be ignored.
它可以视为标量值，或指向包含多个参数的结构的指针，也可以忽略。
It can be treated as a scalar value or a pointer to a structure containing multiple parameters, or it can be ignored.
