您要查找的是不是:
- The null value constant can be implicitly converted to any pointer or handle type, in which case it becomes a null pointer value or null value, respectively. 常量可以隐式转换为任何指针或者句柄类型。
- null pointer value 空指标值
- Null pointer might not compare equal with a variable that has the value 0. 这一句是说空指针不同于“值为0的变量”,因为数值上虽相同,但类型不同,我是这么理解的。
- The program contains a null pointer dereference. 程序包含一个空指针引用。
- The data pointer value is not valid. 数据指针值无效。
- Pointer to message to be posted. A NULL pointer must not be sent. 指向一个被投递的具体的消息.;空指针不会被投递
- If size is 0, then malloc() returns either NULL, or a unique pointer value that can later be successfully passed to free(). 这和数组的一样,你赋值给了一个指针指向的空间,空间不够时就越界了,而用的空间到底是什么谁也不知道!
- Acis error :fail to creat ewire, null pointer to edge given .... 给定的边缘指示无效。。。。为什么呢???
- That is usually a null pointer, but it is not guaranteed. 通常是一个空指针,但并不保证总是这样。
- If the space cannot be allocated, a null pointer is returned. 对于空指针值,而非零值指针!
- Who knows how far that null pointer was passed from method to method before it was ever dereferenced? 谁知道空指针在被丢弃前从方法到方法传递了多远?
- Applying the indirection operator to a null pointer results in an implementation-defined behavior. 如果将间接寻址运算符应用于null指针,则会导致由实现定义的行为。
- JNI puts the interface pointer value at a location specified by its first parameter. JNI将接口指针值放在由第一个参数指定的位置。
- This often happens if a handle is used after it has been freed, or if the handle is the null pointer. 如果在释放句柄后再使用该句柄,或者句柄为空值指针,则通常会发生这种情况。
- Here's what results from dereferencing a NULL pointer on a PC running Version 2.6 of the kernel. 这是通过在一台运行着2.;6内核的PC机上废弃一个NULL指针所引起的。
- This code clips the parameters to allowable ranges, checks for a null pointer assignment, and so on. 此程式码片断的参数允许的范围内,检查空指标转让,等等。
- Dereferencing a NULL pointer in Windows 98/Me will not, of itself, cause any immediately observable problem. 在Windows98/Me中将废弃一个NULL指示器,自然而然的,将不会立刻引起任何明显的问题。
- Allocates or initializes a MYSQL object suitable for mysql_real_connect().If mysql is a NULL pointer, ... 但我已经把机器重新启动再试情况也是一样的.
- Null pointers for two different types are sometimes different. 两种类型的空指针有时不同。
- In particular, we ll look into bug patterns that crop up as null pointer exceptions and discuss how to minimize their occurrence. 我们将特别看一下作为空指针异常而出现的错误模式,并讨论如何将它们的出现次数控制到最少。
