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.
VirtualFree returned successfully.
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.
The call timed out.
The caller does not own the lock.
An event was canceled while a blocked thread or fiber was waiting on it.
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.
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.
