Syntax
struct FGenericPlatformMemoryConstants
Remarks
Struct used to hold common memory constants for all platforms. These values don't change over the entire life of the executable.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
uint64 | AddressLimit | AddressLimit - Second parameter is estimate of the range of addresses expected to be returns by BinnedAllocFromOS(). |
 |
SIZE_T | BinnedAllocationGranularity | This is the "allocation granularity" in Binned malloc terms, i.e. BinnedMalloc will allocate the memory in increments of this value. |
 |
SIZE_T | BinnedPageSize | The size of a "page" in Binned2 malloc terms, in bytes. |
 |
SIZE_T | OsAllocationGranularity | Some platforms have advantages if memory is allocated in chunks larger than PageSize (e.g. VirtualAlloc() seems to have 64KB granularity as of now). |
 |
SIZE_T | PageSize | The size of a physical page, in bytes. |
 |
uint64 | TotalPhysical | The amount of actual physical memory, in bytes (needs to handle >4GB for 64-bit devices running 32-bit code). |
 |
uint32 | TotalPhysicalGB | Approximate physical RAM in GB; 1 on everything except PC. |
 |
uint64 | TotalVirtual | The amount of virtual memory, in bytes. |
