outportb in WIN32
Posted on 1997-01-31
A group at Queen's University is trying to implement the (out,in)portb command in an WIN32 program. We are using the command to directly control the digital port of a National Instruments A/D card. In a 16-bit Dos application, we could simply use the (in,out)portb command, but when trying to create a 32-bit windows GUI application, Borland C++ 5.0 won't compile the program. Checking the help manual and the compatibility list for certain commands, it lists that (in,out)portb is not avaliable to WIN32. Is there any way around this in a WIN95 environment to use the outportb command in a 32-bit application. If so, how would one do it? (does it possibly involve accessing the EISA.vxd file in windows 95?)
Thanks for such consideration,
