![]() Returns AX = FFFFh, if mouse support is available, otherwise, returns Ax = 0.This function is present in “ graphics.h “ header file. To switch our output window in Graphic mode steps are listed below:Įnable Graphic mode: For enabling the graphics mode use initgraph() function which is used to initialize the graphics mode. First is the non-graphic mode and the second is Graphic mode, Here we use graphic mode. Now there are two ways to display mouse pointer on C/C++ screen. Use two registers to communicate to a device driver one for input and one for output and send value to device driver through the input register and receive information in it embedded in the output register. These are basically UNION of type REGS defined in “ dos.h“. Use of address registers is also required to access these port. Each device provided by a computer has a unique port which is a hexadecimal value that is designed to be machine-independent enhancing the portability of the program. The idea is to use interrupts to get access to this driver. In actual the communication with the mouse directly is not possible but through the driver provided. The idea is to tell a mouse to do anything on the output screen.

The mouse position is provided in physical/ unscaled Windows pixels and in coordinates scaled by DPI-virtualization. MPos especially considers High-DPI monitors and DPI scaling of Windows 10.

Not all of the code is tested but what i want to look at is line 49 and 50, where i get the moue position.
