内存泄漏(Memory Leak)是指程序失去对一段已分配内存的控制,导致持续占用已经不再使用的内存空间而无法释放。这个错误最终会占满所有内存而导致内存溢出(Out of Memory, OOM)。 例如,在下面的bad.c代码中,f()函数申请了10个int的内存空间却不释放(Problem 2);放在指针x中的内存空间地址随着f()的析构而消失,无...

Checking memory_leak.cpp... [Memory_leak.cpp:4]: (error) Memory leak: array 1. 6.2 检测空指针解引用 int main() { int *ptr = nullptr; *ptr = 10; return 0; } 1. 2. 3. 4. 5. 6. 7. 在这段代码中,我们创建了一个空指针ptr,然后试图对其进行解引用。这将导致未定义的行为。
The check result can help locate problems of Layer 3 forwarding software resource leak and residual Layer 3 forwarding hardware entries. The three parameters, cycle-interval, interval, and entry-number, together determine the periodic l3-forward-entry check process. For example, the device has a ...

The KMA allows a kernel subsystem to allocate and free memory as needed. Rather than statically allocating the maximum amount of memory it is expected to require under peak load, the KMA divides requests for memory into three categories: small (less than 256 bytes), large (512 to 4 Kbytes)...
