Function GetDiskGeometry

Driver function GetDiskGeometry is called by RTFiles-32 to inquire the size and other characteristics of a disk:

int RTFAPI GetDiskGeometry(void *               DriveData, 
                           RTFPartitionRecord * DiskGeometry, 
                           BYTE *               MediaDescriptor);

Parameters

DriveData

Pointer to the DeviceData found in the device list for the device.

DiskGeometry

Pointer to an RTFPartitionRecord record to be returned. For disks with more than 4G sectors, a record of type RTFPartitionRecord64 should be returned.

MediaDescriptor

Pointer to a media descriptor to be returned.

return value

If the function succeeds, it returns RTF_NO_ERROR. If it fails, the return value is a negative error code.
