```
#include <zircon/syscalls.h>

zx_status_t zx_vmar_destroy(zx_handle_t handle);
```

## DESCRIPTION

`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.
