IHostMemoryManager::VirtualFree Method
Serves as a logical wrapper for the corresponding Win32 function. The Win32 implementation of VirtualFree releases, decommits, or releases and decommits a region of pages within the virtual address space of the calling process.
HRESULT VirtualFree (
[in] LPVOID lpAddress,
[in] SIZE_T dwSize,
[in] DWORD dwFreeType
);
Parameters
- lpAddress
[in] A pointer to the base address of the virtual memory pages to be freed.
- dwSize
[in] The size, in bytes, of the region to be freed.
- dwFreeType
[in] The type of freeing operation.
Return Value
| HRESULT | Description |
|---|---|
S_OK |
VirtualFree returned successfully. |
HOST_E_CLRNOTAVAILABLE |
The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully. |
HOST_E_TIMEOUT |
The call timed out. |
HOST_E_NOT_OWNER |
The caller does not own the lock. |
HOST_E_ABANDONED |
An event was canceled while a blocked thread or fiber was waiting on it. |
E_FAIL |
An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE. |
HOST_E_INVALIDOPERATION |
An attempt was made to free memory that was not allocated through the host. |
Remarks
VirtualFree frees virtual memory pages associated with the lpAddress parameter through an earlier call to the IHostMemoryManager::VirtualAlloc Method function. Attempts to free memory that was not allocated through the host should return HOST_E_INVALIDOPERATION.
The semantics are identical to those of the Win32 implementation of VirtualFree. For more information, see the Windows Platform documentation.
