Functions
void *	vm::ReserveAddressSpace (size_t size, size_t commitSize=g_LargePageSize, PageType pageType=kDefault, int prot=PROT_READ|PROT_WRITE)
	reserve address space and set the parameters for any later on-demand commits. More...
void	vm::ReleaseAddressSpace (void *p, size_t size=0)
	release address space and decommit any memory. More...
bool	vm::Commit (uintptr_t address, size_t size, PageType pageType=kDefault, int prot=PROT_READ|PROT_WRITE)
	map physical memory to previously reserved address space. More...
bool	vm::Decommit (uintptr_t address, size_t size)
	unmap physical memory. More...
bool	vm::Protect (uintptr_t address, size_t size, int prot)
	set the memory protection flags for all pages that intersect the given interval. More...
void *	vm::Allocate (size_t size, PageType pageType=kDefault, int prot=PROT_READ|PROT_WRITE)
	reserve address space and commit memory. More...
void	vm::Free (void *p, size_t size=0)
	decommit memory and release address space. More...
void	vm::BeginOnDemandCommits ()
	install a handler that attempts to commit memory whenever a read/write page fault is encountered. More...
void	vm::EndOnDemandCommits ()
	decrements the reference count begun by BeginOnDemandCommit and removes the page fault handler when it reaches 0. More...
