IHostMemoryManager Interface

  • Article

Provides methods that allow the common language runtime (CLR) to make virtual memory requests through the host, instead of using the standard Win32 virtual memory functions.

Methods

Method Description
AcquiredVirtualAddressSpace Method Notifies the host that the common language runtime (CLR) has acquired the specified memory from the operating system.
CreateMAlloc Method Gets an interface pointer to an IHostMAlloc instance that is used to request memory allocations from a heap created by the host.
GetMemoryLoad Method Gets the amount of physical memory that is currently being used, as reported by the host.
NeedsVirtualAddressSpace Method Notifies the host that the CLR is going to attempt to use the specified memory.
RegisterMemoryNotificationCallback Method Registers a pointer to a callback function that the host invokes to notify the CLR of the current memory load on the computer.
ReleasedVirtualAddressSpace Method Notifies the host that the CLR has finished using the specified memory.
VirtualAlloc Method Serves as a logical wrapper for the corresponding Win32 function, which reserves or commits a region of pages in the virtual address space of the calling process.
VirtualFree Method Serves as a logical wrapper for the corresponding Win32 function, which releases, decommits, or releases and decommits a region of pages within the virtual address space of the calling process.
VirtualProtect Method Serves as a logical wrapper for the corresponding Win32 function, which changes the protection on a region of committed pages in the virtual address space of the calling process.
VirtualQuery Method Serves as a logical wrapper for the corresponding Win32 function, which retrieves information about a range of pages in the virtual address space of the calling process.

Remarks

IHostMemoryManager also provides methods for the CLR to obtain a pointer through which to make memory requests on the heap and to get the level of memory pressure in the process, as reported by the host.
