发帖数: 6180 | 1 Is it risk to use void pointer in the following case:
typedef struct
{
void *next;
UINT16 xx;
UINT16 yy;
byte zz;
} a;
mostly, I think
struct a
{
struct a *next;
UINT16 xx;
UINT16 yy;
byte zz;
};
could be better, but is there any risk to use void pointer? what we should
pay attention in order to carefully manipulate the pointer in this case?

this example, just some legacy code.

typedef struct _a
{
struct _a *next;
UINT16 xx;
UINT16 yy;
byte zz;
}a;
