What is "Defeating" DMA?

Ok all I know is that DMA is a process where the CPU isnt used to do the hard work of transfering and reading/writing memory.

But what do you guys mean by "Defeating" DMA

Are you trying to say there is a "lock" on reading an adress or something...I dunno Ive never done anything like this before and im curious...

dma means dynamic memory alocation that means if you need memory for a variable like health points then the programm gets some space writes there the health points works with them and then frees the memory space and when it comes again to the point where it needs space for the healthpoints it gets space again and this space is everytime at another location and to defeat means that you make the programm write the healthpoints at the same spot in memory so you know where it is to read it
