Subject: Writing to physical memory


	
	I have a question about which is a faster way to write into
physical (real mode) memory:
	Is it faster to use dosmemput() or movedata() ?
	additionally the selectors used in in movedata(), are they a constant?
	ie can I calcualte what the selectors are and never recalculate thme?
		like try:

			unsigned VID_ADDR=0xA0000;
			unsigned src_selector,dst_selector;
			unsigned char *buff;

			Init()
			{
				buff=malloc(320*200);
				if (buf==NULL) exit(0);
				src_selector=_go32_my_ds();
				dst_selector=_go_32_conventionl_memory();
					 //  I may have the wrong 
function on whow to get the conventional memory selector.
			}

			Refresh()
			{
				movedata(dst_selector,VID_ADDR,
					 src_selector,buff,
					 320*200);
			}

or is there a faster way than movedata() or dosmemput() ?
