The Question is:
Using 'C' - I am trying to call sys$getdviw() to return the name of a device.
This works fine when compiling /POINTER=32 but when I compile with /POINTER=64
I receive an ACCVIO:
I suspect that my home-brewed itmlst is to blame. Where can I find a 'robust'
definition for itmlst?
The Answer is :
The itemlist you are using is apparently a 32-bit structure; please
see the pragmas for establishing the pointer sizes around the structure
declarations or code involved.
Alternatively, for details on operating with sixty-four bit addressing
and for the 64-bit itemlist structures, please see the OpenVMS
Programming Concepts Manual chapter on the topic -- a section
comparing 32- and 64-bit itemlists is included within the chapter.
