# anv_memleak
RT-Thread 软件包，帮助检查内存泄漏。

    int anv_memleak_example(int argc, char const *argv[])
    {
        // Initialization
        anv_leak_info **leaks;
        size_t leaks_count;

        anv_leaks_init(stdout);

        // Your Code Here
        void *mem = malloc(10);
        anv_leaks_quickpeek();

        // free(mem);
        // anv_leaks_quickpeek();

        // Get the result
        anv_leaks_stats stats;
        anv_leaks_get_stats(&stats);

        rt_kprintf("[total] %d allocated, %d freed\n", stats.total_allocated, stats.total_freed);
        rt_kprintf("[count] %d malloc, %d free\n", stats.malloc_count, stats.free_count);
        rt_kprintf("[count] %d calloc, %d realloc\n", stats.calloc_count, stats.realloc_count);

        // Get all leaks
        anv_leaks_get_leaks(&leaks, &leaks_count);

        rt_kprintf("\n");
        rt_kprintf("[total] %d leaks\n", leaks_count);

        for (int i = 0; i < leaks_count; ++i)
        {
            rt_kprintf("[%s] line %d, %d bytes\n", leaks[i]->filename,  leaks[i]->line, leaks[i]->bytes);
        }
        anv_leaks_free_info(leaks, leaks_count);

      return 0;
    }

快速定位到哪个文件，哪一行出现了内存泄漏。
