Adds a file system to the paging device table.

int vm_mount (type, ptr, nbufstr) int type; int (*ptr)(); int nbufstr;
| type | Specifies the type of device. The type parameter must have a value of D_REMOTE. |
| ptr | Points to the file system's strategy routine. |
| nbufstr | Specifies the number of buf structures to use. |
The vm_mount kernel service allocates an entry in the paging device table for the file system. This service also allocates the number of buf structures specified by the nbufstr parameter for the calls to the strategy routine.
The vm_mount kernel service can be called from the process environment only.
| 0 | Indicates a successful operation. |
| ENOMEM | Indicates that there is no memory for the buf structures. |
| EINVAL | Indicates that the file system strategy pointer is already in the paging device table. |
The vm_mount kernel service is part of Base Operating System (BOS) Runtime.
