Parameters
numPages |
Number of memory pages that should be reserved |
type |
Type of memory to allocate |

Description
This function reserves a range of physical memory addresses on the system bus which the AGP controller will respond to. If this function succeeds, the AGP controller can respond to the reserved physical address range on the bus. However you must first call AGP_commitPhysical to cause this memory to actually be committed for use before it can be accessed.
