Tape Media Changer driver entry points
If the Removable Storage Manager is stopped, then the following
user-callable tape media changer driver entry points are supported
under ibmcgxxx.sys:
- CreateFile
- CloseHandle
- DeviceIoControl
Users who want to write application programs to issue commands to IBM® TotalStorage™ device drivers must obtain a license to the MSDN and the Microsoft Visual C++ Compiler. Users also need access to IBM hardware reference manuals for IBM TotalStorage devices.
Programs that access the IBM TotalStorage device driver
must complete the following steps:
- Include the following files in the application.
#include <ntddscsi.h> #include <ntddchgr.h> #include <ntddtape.h> /* Modified as indicated below */ - Add the following lines to ntddtape.h.
