first of all, know how virtualalloc() works: when reserve blocks of memory, addresses aligned 64k boundaries, (a value can obtained getsysteminfo() ), when commit pages, them on page size boundary, 4k. the thing can't get, why if call virtualalloc() mem_reserve flag (so i'm reserving pages) , specify size, let's 4096, won't able grow further region 64k? what i'm saying is: when commit pages can use memory 4k because windows alignes these commits page size (of course, i'm commiting pages!), when i'm reserving regions of memory, shouldn't windows align size of region pass virtualalloc() 64k? "wasted" 15 pages go? so if reserve 4096 bytes, shouldn't able commit more pages until 65536 bytes? doesn't seem so, because if try this, virtualalloc() fails error_invalid_address last error code. but why? if windows reserve pages on 64k boundaries, , reserve pages on less size, loose pages don't reserve forever? because seems t...
