| 3 | <p> | |
| 4 | <strong>Function</strong> - Handle kernel operation request aimed at a given memory manager. | |

| 7 | <strong>boolean_t seqnos_memory_object_server</strong> | |
| 8 | <strong>(mach_msg_header_t</strong> <var>request_msg</var>, | |

| 11 | <h3>PARAMETERS</h3> | |
| 12 | <dl> | |
| 13 | <p> | |
| 14 | <dt> <var>in_msg</var> | |
| 15 | <dd> | |
| 16 | [pointer to in structure] | |
| 17 | The memory manager message received from | |
| 18 | the kernel. | |
| 19 | <p> | |
| 20 | <dt> <var>out_msg</var> | |
| 21 | <dd> | |
| 22 | [out structure] | |
| 23 | A reply message. No messages to a memory manager | |
| 24 | expect a direct reply, so this field is not used. | |
| 25 | </dl> | |
| 26 | <h3>DESCRIPTION</h3> | |
| 27 | <p> | |
| 28 | The <strong>seqnos_memory_object_server</strong> function is the MIG generated server | |
| 29 | handling function to handle messages from the kernel targeted to a memory | |
| 30 | manager. | |
| 31 | <p> | |
| 32 | A \*Vmemory manager\*O | |
| 33 | is a server task that responds to specific messages from the | |
| 34 | kernel in order to handle memory management functions for the kernel. The | |
| 35 | <strong>seqnos_memory_object_server</strong> function performs all necessary argument | |
| 36 | handling for a kernel message and calls one of the memory manager functions to | |
| 37 | interpret the message. | |
| 38 | <h3>NOTES</h3> | |
| 39 | <p> | |
| 40 | <strong>seqnos_memory_object_server</strong> differs from <strong>memory_object_server</strong> | |
| 41 | in that it | |
| 42 | supplies message sequence numbers to the server interfaces. | |
| 43 | <h3>RETURN VALUES</h3> | |
| 44 | <dl> | |
| 45 | <p> | |
| 46 | <dt> <strong>TRUE</strong> | |
| 47 | <dd> | |
| 48 | The message was handled and the appropriate function was called. | |
| 49 | <p> | |
| 50 | <dt> <strong>FALSE</strong> | |
| 51 | <dd> | |
| 52 | The message did not apply to this memory management interface and | |
| 53 | no other action was taken. | |
