malloc()是C语言中的一个函数,用于动态分配内存空间。它的原型定义在stdlib.h头文件中。 malloc()函数的作用是在程序运行时从堆中分配一块指定大小的内存空间,并返回该内存空间的首地址。这块内存空间可以用来存储各种类型的数据。 在给定的问答内容中,提到了C语言中的top size已损坏。这可能是指在使用malloc()函...

我试图用C语言编写一个非常简单的压缩器,但在代码中遇到了错误“Heap has been corrupted”。我查了一下,错误似乎是因为这一行: ptr = (char*)malloc(count * sizeof(char)); 当我将大小从count改为1000时,它可以工作,我试着调试,看看是否有差异,但我找不到它,我知道可能有某种溢出,但我不明白为什么和什...
大致流程 __libc_malloc 我们平时所用的malloc函数在glibc中实际调用的是__libc_malloc函数,通过string_alias宏强命名为malloc使用的。__libc_malloc函数主要操作为 判断__malloc_hook是否有指定hook,有则直接调用__mall

The function void operator delete(void *, size_t) was a placement delete operator corresponding to the placement new function void * operator new(size_t, size_t) in C++11. With C++14 sized deallocation, this delete function is now a usual deallocation function (global delete operator). The...
