SetTapeParameters

The SetTapeParameters function either specifies the block size of a tape or configures the tape device.

DWORD SetTapeParameters(
  HANDLE hDevice,     // handle of open device
  DWORD dwOperation,  // type of information to set
  LPVOID lpTapeInformation 
                      // address of buffer with information to set
);
 

Parameters

hDevice
Identifies the device for which to set configuration information. This handle is created by using the CreateFile function.
dwOperation
Specifies the type of information to set. This parameter must be one of the following values:
Value Description
SET_TAPE_MEDIA_INFORMATION Sets the tape-specific information specified by the lpTapeInformation parameter.
SET_TAPE_DRIVE_INFORMATION Sets the device-specific information specified by lpTapeInformation.

lpTapeInformation
Points to a structure that contains the information to set. If the dwOperation parameter is SET_TAPE_MEDIA_INFORMATION, lpTapeInformation points to a TAPE_SET_MEDIA_PARAMETERS structure.

If dwOperation is SET_TAPE_DRIVE_INFORMATION, lpTapeInformation points to a TAPE_SET_DRIVE_PARAMETERS structure.

Return Values

If the function succeeds, the return value is NO_ERROR.
