it will not be destroyed by the garbage collector and will remain in the memory forever and can become a reason for a memory leak. An example of this situation can be an event
Effects of Memory Leak in C Memory leakscan cause a lot of problems in a program. If left unchecked, amemory leakcan cause the program to crash or stop running, which can lead to data loss or corruption. Moreover, since the program is consuming more memory than it needs, it can impact...

使用一段C程序可以测试泄露的问题,C程序如下c_example如下所示: 点击(此处)折叠或打开 #include <stdlib.h> #include <stdio.h> void foo(int size) { int* data = malloc(sizeof(int) * size); // Uncomment this to stop leak //free(data); ...
The size of the leak depends on the value of CURLOPT_XOAUTH2_BEARER; in this example it is 260 because the token is 65 characters long (including '\0') times 4. I expected the following Repeatedly performing HTTP requests with the same handle when a bearer token is set with the CURL...
