这个类型转换怎么修改？

Question

这段程序是freertos的一部分。在c编译器中编译通过，在c++编译器中报错。如下

....\FreeRTOS\portable\MemMang\heap_2.c(295): error: #415: no suitable constructor exists to convert from "std::uint8_t *" to "A_BLOCK_LINK"

下面是出错代码

/* xStart is used to hold a pointer to the first item in the list of free
blocks.  The void cast is used to prevent compiler warnings. */

// xStart.pxNextFreeBlock = ( void * ) pucAlignedHeap;

xStart.pxNextFreeBlock = static_cast<A_BLOCK_LINK>(pucAlignedHeap);
xStart.xBlockSize = ( size_t ) 0;

这个是他的定义
typedef struct A_BLOCK_LINK

{
struct A_BLOCK_LINK pxNextFreeBlock; /<< The next free block in the list. /
size_t xBlockSize; /<< The size of the free block. */
} BlockLink_t;

/* Create a couple of list links to mark the start and end of the list. */
static BlockLink_t xStart, xEnd;

请问我应该如何修改这一部分？

你要在C中用结构体数组来代替。。。。。。。。。。。
