void vm_det (eaddr) caddr_t eaddr;
| eaddr | Specifies the effective address in the current address space. The region containing this address is to be unmapped and deallocated. |
The vm_det kernel service unmaps the region containing the eaddr parameter and deallocates the region, adding it to the free list for the current address space.
The vm_det kernel service assumes an address space model of fixed-size virtual memory objects and address space regions.
Attention: If the region is not mapped, or a system region is referenced, the system will halt.
The vm_det kernel service can be called from either the process or interrupt environment.
The vm_det kernel service is part of Base Operating System (BOS) Runtime.
The vm_att kernel service.
