ReadSectors Method

Reads data from sectors of a disk.

Syntax

int ReadSectors(qint64 lVolumeHandle, qint64 lStartingSector, int iSectorCount, QByteArray& qbaBuffer);

Remarks

This method reads data from sectors of the disk identified by VolumeHandle.

The value passed for VolumeHandle must be a volume handle obtained from the OpenVolume method; refer to its documentation for more information.

The StartingSector parameter specifies which sector to begin reading data from.

The SectorCount parameter specifies how many sectors of data to read.

The data from the disk is read into Buffer, which must be large enough to contain all of the requested data; i.e., SectorCount * SectorSize, where SectorSize is the value returned by GetSectorSize.

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
