我有以下代码涉及struct
包括指针变量,我无法检索每个变量的正确内容。
有人可以帮我吗?
struct MyData
{
ULONG Value[3];
wchar_t *Str1;
int Str1Len;
wchar_t *Str2;
int Str2Len;
};
// In the driver, on method that receives commands i have following:
struct MyData *pData = (struct MyData*) Irp->AssociatedIrp.SystemBuffer;
DbgPrint("0x%x \n 0x%x \n 0x%x \n %s \n %d \n %s \n %d", &pData->Value[0], &pData->Value[1], &pData->Value[2], &pData.Str1, &pData->Str1Len, &pData->Str2, &pData->Str2Len);
答案 0 :(得分:0)
DbgPrint
的调用与调用printf
非常相似,因此您应该传递值,而不是值的地址。所以
DbgPrint("0x%x \n 0x%x \n 0x%x \n %s \n %d \n %s \n %d", &pData->Value[0], // etc...
应该是
DbgPrint("0x%x \n 0x%x \n 0x%x \n %s \n %d \n %s \n %d", pData->Value[0], // etc...
