<http://stackoverflow.com/questions/43336683/how-to-store-binary-file-data-in-structure#>
Hi all,
I have a file shown below(Material.dat) which is binary file , I want to
read data from the file and put in the structure(Header) for that I have
used GetRecord() function.
HANDLE hFileMac = ::CreateFile(_T("Material.dat"), GENERIC_READ,
FILE_SHARE_READ, NULL,
OPEN_EXISTING, FALSE ? FILE_FLAG_SEQUENTIAL_SCAN : FILE_ATTRIBUTE_NORMAL,
NULL);
if (!(hFileMac != INVALID_HANDLE_VALUE))
{
return;
}
GetRecord(hFileMac, RECORD_NUMBER, sizeof(Header), reinterpret_cast<void
*>(&Header));
My doubt is what to pass as a record number to Get Record() function?
GetRecord(hFileMac, RECORD_NUMBER, sizeof(Header),
reinterpret_cast(&Header));
int GetRecord(HANDLE hFile, int RecordNumber, int RecordSize, void *RecordPtr){
if (RecordNumber <= 0 || RecordSize <= 0)
return 1;
LONG lOffset = (RecordNumber - 1) * RecordSize;
if (SetFilePointer(hFile, lOffset, NULL, FILE_BEGIN) == 0xFFFFFFFF)
return 2;
DWORD dwSize;
if (::ReadFile(hFile, RecordPtr, RecordSize, &dwSize, NULL) == 0)
return 3;
return 0;}
