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 );
[in] A pointer to the base address of the virtual memory pages to be freed.
[in] The size, in bytes, of the region to be freed.
[in] The type of freeing operation.
|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.|
VirtualFree frees virtual memory pages associated with the
lpAddress parameter through an earlier call to the IHostMemoryManager::VirtualAlloc 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.
