我的任务
分享API函数ReadFile怎么得到读得的内容？
BOOL ReadFile(
HANDLE hFile, // handle of file to read
LPVOID lpBuffer, // address of buffer that receives data
DWORD nNumberOfBytesToRead, // number of bytes to read
LPDWORD lpNumberOfBytesRead, // address of number of bytes read
LPOVERLAPPED lpOverlapped // address of structure for data
);
HANDLE hFile, // handle of file to read
LPVOID lpBuffer, // address of buffer that receives data
DWORD nNumberOfBytesToRead, // number of bytes to read
LPDWORD lpNumberOfBytesRead, // address of number of bytes read
LPOVERLAPPED lpOverlapped // address of structure for data
);

TCHAR szBuf[32];
DWORD dwRead;
ReadFile(fHandle,szBuf,32,&dwRead,NULL);
在单步调试时，看到szBuf是乱码？
我的那文件里只有一个大整数，123456789

//create a file and get its file handle
HANDLE hFile=CreateFile(...);
//define an array for receiving data
BYTE recv = new BYTE[500];
int recv_need_byte;
//invoke
ReadFile(hFile,recv,500,&recv_need_byte,0);
HANDLE hFile=CreateFile(...);
//define an array for receiving data
BYTE recv = new BYTE[500];
int recv_need_byte;
//invoke
ReadFile(hFile,recv,500,&recv_need_byte,0);

读到的内容在LPVOID lpBuffer, // address of buffer that receives data 中
