Windbg将指针视为有符号整数

Question

struct Node
{
struct NodeY NY;
int data;
};

When I do this, for an instance pointer 'N' of that structure

2: kd> ?poi(poi(N))
Evaluate expression: -70368698399456 = ffffc000`02ba8520

basically I want to use something like this

bp igdkmd64!KmRender+0x199 ".if (@@(N) > 0x1){}.else {gc}"

So, most of the cases it is true, but as windbg treats it has signed integer, the above conditional breakpoint is always false as @@(N) is always computed as negative.

How can I get a quantity comparison of 2 memory addresses?

Answer 1

kd> ?? ( int64 ) @@(ffffc00002ba8520) > 1
bool false
kd> ?? ( unsigned int64 ) @@(ffffc00002ba8520) > 1
bool true
