Indicates that no more references will be made to a virtual memory object obtained using the as_geth64 kernel service.
#include <sys/types.h> #include <sys/errno.h> #include <sys/vmuser.h> #include <sys/adspace.h> int as_puth64 ( addr64, vmhandle ) unsigned long long addr64; vmhandle_t vmhandle;
| Item | Description |
|---|---|
| addr64 | Specifies the virtual memory address that the virtual memory object handle was obtained from. This must be the same address that was given to the as_geth64 kernel service previously. |
| vmhandle | Describes the virtual memory object that will no longer be referenced. This handle must have been returned by the as_geth64 kernel service. |
The as_puth64 kernel service is used to indicate that no more references will be made to the virtual memory object returned by a call to the as_geth64 kernel service. The virtual memory object must be detached from the address space already, using either as_det64 or vm_det service.
Failure to call the as_puth64 kernel service may result in resources being permanently unavailable for re-use.
If, for some reason, it is known that the virtual memory object cannot be deleted, the as_getsrval64 kernel service may be used instead of the as_geth64 kernel service. This kernel service does not require that the as_puth64 kernel service be used.
The as_puth64 kernel service assumes an address space model of fixed-size virtual memory objects.
This service will operate correctly for both 32-bit and 64-bit user address spaces. It will also work for kernel processes (kprocs).
The as_puth64 kernel service can be called from the process environment only.
