覆盖malloc的问题 [英] Problem in overriding malloc

问题描述

我正在尝试通过这样做来覆盖malloc。

I am trying to override malloc by doing this.

#define malloc(X) my_malloc((X))

void* my_malloc(size_t size)
{

    void *p = malloc(size);
    printf ("Allocated = %s, %s, %s, %x\n",__FILE__, __LINE__, __FUNCTION__, p);
    return p;
}

但是，这将无限期地递归调用my_malloc（因为在my_malloc内部调用了malloc） 。我想在my_malloc而不是宏实现中调用C malloc函数。

However, this is indefinitely calling my_malloc recursively (because of malloc call inside my_malloc). I wanted to call C malloc function inside my_malloc and not the macro implementation. Could you please let me know how to do that?

谢谢。

推荐答案

问题已解决：

void* my_malloc(size_t size, const char *file, int line, const char *func)
{

    void *p = malloc(size);
    printf ("Allocated = %s, %i, %s, %p[%li]\n", file, line, func, p, size);
    return p;
}
#define malloc(X) my_malloc( X, __FILE__, __LINE__, __FUNCTION__)
