"Pixels"

Hi Tom & Dave,

 DVH> How do you write a pixel to the console using BCOS2???

TT>Mmh, PRCP.INF says the following:

TT>Note: Although graphics mode support is provided in 
TT>VioSetMode, this support is not provided by the Base Video 
TT>Handlers provided with OS/2.

TT>Does anybody know how to do graphics in console mode ?

There is a an API called VioGetPhysBuf() that will allow you to access the
physical video memory. This is a 16-bit API, it requires full-screen mode
and is totally device dependent. Not a recommended approach.

Moreover, it requires one to write the video data in bulk, not just a single
pixel. This is sensible for performance reasons, but does not answer the
original question.

TT>If not, you may have to resort to making a PM program (=GUI).

The Gpi...() family of API calls make this a much preferred approach. All
the adapter handling is done by the video drivers. It also avoids the
problems BCOS/2 has with 16-bit addressing, as the Gpi...() calls are
32-bit.

Regards

Dave
