Destroy a virtual memory address region.
#include <zircon/syscalls.h> zx_status_t zx_vmar_destroy(zx_handle_t handle);
zx_vmar_destroy() unmaps all mappings within the given region, and destroys all sub-regions of the region. Note that this operation is logically recursive.
This operation does not close handle. Any outstanding handles to this VMAR will remain valid handles, but all VMAR operations on them will fail.
The root VMAR, as obtained by
zx_process_create(), cannot be destroyed.
zx_vmar_destroy() returns ZX_OK on success.
ZX_ERR_BAD_HANDLE handle is not a valid handle.
ZX_ERR_WRONG_TYPE handle is not a VMAR handle.
ZX_ERR_BAD_STATE This region is already destroyed.
ZX_ERR_NOT_SUPPORTED handle is a root VMAR.
