Removes a file system from the paging device table.

int vm_umount (type, ptr) int type; int (*ptr)();
| type | Specifies the type of device. The type parameter must have a value of D_REMOTE. |
| ptr | Points to the strategy routine. |
The vm_umount kernel service waits for all I/O for the device scheduled by the pager to finish. This service then frees the entry in the paging device table. The associated buf structures are also freed.
The vm_umount kernel service can be called from the process environment only.
| 0 | Indicates successful completion. |
| EINVAL | Indicates that a file system with the strategy routine designated by the ptr parameter is not in the paging device table. |
The vm_umount kernel service is part of Base Operating System (BOS) Runtime.
