Ask the Wizard Questions

Get device info from Fortran

The Question is:

I am using Fortran. How can I test inside my Fortran program if some drive (for example DKF200) is allocated or not

The Answer is:

You can call the SYS$GETDVI service and ask for the DVI$_DEVCHAR flags longword. The DEV$V_ALL flag bit will be set if the device is allocated. You may find using LIB$GETDVI an easier interface. For more information, see the OpenVMS System Services Reference Manual (for SYS$GETDVI) and the LIB$ Run-Time Library Routines Reference Manual (for LIB$GETDVI).
