If the calling method does not explicitly check for a null pointer , it may attempt to dereference the return value and trigger a null - pointer exception 如果调用方法没有明确地检查空指针，它可能会尝试丢弃返回值并触发一个空指针异常。
This bug occurs when your software throws a null - pointer exception , a hard - to - diagnose problem , due to the misrepresentation of a recursive datatype 当您的软件抛出空指针异常时这个错误发生，因为递归数据类型的错误表示，所以这是个难以诊断的问题。
Code analysis tool detects common coding errors , such as buffer overrun , un - initialized memory , null pointer dereference , and memory and resource leaks 代码分析工具用于检测常见的编码错误，例如缓冲区溢出、内存未初始化、空指针取消引用，以及内存和资源泄露。
A null pointer exception is returned in the application server file systemout . log when ifxbblob or ifxcblob is created using a serialized object and sent to the server 当使用串行化的对象创建ifxbblob或ifxcblob并将它们发送到服务器时，会返回一个空指针异常。
In c , we make a data structure store data of any type by using void pointers to the data rather than by maintaining private copies of the data in the data structure itself 在c语言中，我们通过使用空指针，而不是通过维护非公开的数据备份，使数据结构存储任何类型的数据。
As you might have guessed , i call this pattern the null flag bug pattern because it is caused by inconsistently using null pointers as flags for exceptional conditions 您可能会猜想，之所以称这种模式为空标志错误模式，是因为它是不一致地使用空指针作为异常情况的标志引起的。
Warning c6308 : realloc may return null pointer : assigning a null pointer to variable , which is passed as an argument to realloc , will cause the original memory block to be leaked 警告c6308 ： “ realloc ”可能返回空指针:将空指针赋给< variable > (后者将作为参数传递给“ realloc ” )将导致原始内存块泄漏
Note that the host must not throw an elementnameinvalid exception when the name parameter is a null pointer , as a null pointer is a valid argument used to request engine - level data 请注意，当名称参数为空指针时，宿主一定不能引发elementnameinvalid异常，因为空指针是用来请求引擎级数据的有效变量。
Pointer to variable that receives the completion key value associated with the file handle whose i / o operation has completed . completion key is per - file key that is specified in call to createiocompletionport 所以在使用这个函数的时候只需要将此处填一相应数据结构的空指针就可以了.上面的解释只有大家自己摆平了
[ out ] pointer to variable that receives the completion key value associated with the file handle whose i / o operation has completed . completion key is per - file key that is specified in call to createiocompletionport 所以在使用这个函数的时候只需要将此处填一相应数据结构的空指针就可以了.上面的解释只有大家自己摆平了
