A specific case of using assembly in C...
In a windows environment, how different is it to set the video mode to 13h for example? This is in comparison to a DOS setting where:
MOV ax, 0013h
INT 10h
...would do the trick.
My aim has been to write decoders of various file formats in flavors of BASIC, C, and Ruby (along with others like C++/C# when appropriate). I have gotten to the point where I would rather not implore a library in C or Ruby when all that is needed is to just set a graphics mode and plot a single pixel when dealing with image file formats. I want to use assembly to perform functions that choice languages do not natively support.
I understand things are different in Windows and wonder how many 'rings' of protection, system calls, (and fire) I would have to jump through in order to achieve something like this with assembly. To keep things relevant to this sub-forum, can anyone give me some directions for doing this in C on an x86 machine?
Looking forward to thoughts on this.
