8086 assembly right mouse click interrupts

Question

I am working on a project in 8086 assembly on windows machine and I need to know which mouse button has been clicked. What are the interrupts for this? or how do I go about

Answer 1

On a "DOS" machine, look into Software Interrupt 0x33.
Command AH = 0x03 returns the mouse button pressed in register CX (along with mouse coordinates and other info, in other registers).

If available, it is of course much easier to user the Windows API for this purpose, as indicated in matja's answer.
