结构体与指针的初始化

[Tobby0419]

struct AHRSInfo
{
double GyroX;
double GyroY;
double GyroZ;

double ACC_X;
double ACC_Y;
double ACC_Z;

float Pitch;
float Roll;
float Heading;

};
typedef struct {
UINT *FrameNO;
AHRSInfo* IMUInfo;
UINT Lidardata[LIDARPOINTDATANO];
} BIN_Lidarpoint;

FILE *Bin_Sfp;
UINT RD_Frame, RD_IMUNO,RD_LNO ;
RD_Frame = 0 ;
RD_IMUNO = 0;
RD_LNO = 0;
BIN_Lidarpoint *Read_Line ;

memset (&Read_Line->FrameNO, 0, sizeof (UINT));
memset (Read_Line->IMUInfo, 0, sizeof (AHRSInfo));
memset (Read_Line->Lidardata, 0, sizeof (Read_Line->Lidardata));

if( (Bin_Sfp = fopen(Bin_Filename,"r")) == NULL )
{
MessageBox("文件打开失败", "Error", MB_ICONEXCLAMATION|MB_OK);
return ;
}

RD_Frame = fread(Read_Line->FrameNO,sizeof(long) ,1,Bin_Sfp);

RD_IMUNO = fread(Read_Line->IMUInfo, sizeof(AHRSInfo) ,1,Bin_Sfp);

RD_LNO = fread(Read_Line->Lidardata ,404 ,1,Bin_Sfp);

为啥 会报错呢，编译没有错误，这个结构体和指针的初始化该是怎么样的啊？

BIN_Lidarpoint *Read_Line ;//这句只是声明了一个变量，还没有分配空间，下面执行的memset (&Read_Line->FrameNO, 0, sizeof (UINT));当然会当机了
改成

BIN_Lidarpoint *Read_Line = malloc(sizeof(BIN_Lidarpoint));
//memset (&Read_Line->FrameNO, 0, sizeof (UINT));//Read_Line->FrameNO是一个未分配空间的指针，不能这样memset
Read_Line->FrameNO = 0;
//memset (Read_Line->IMUInfo, 0, sizeof (AHRSInfo));//Read_Line->IMUInfo是一个未分配空间的指针，不能这样memset
Read_Line->IMUInfo = 0; 
memset (Read_Line->Lidardata, 0, sizeof (Read_Line->Lidardata));
