25 | <p> | |
26 | The <strong>clock_reply_server</strong> function is the MIG generated server handling | |
27 | function to handle messages from the kernel corresponding to | |
28 | clock alarms. Such | |
29 | messages are delivered to the alarm reply port named in a <strong>clock_alarm</strong> | |
30 | call. The <strong>clock_reply_server</strong> function performs all necessary | |
31 | argument handling for | |
32 | this kernel message and calls the appropriate handling function. These functions | |
33 | must be supplied by the caller. | |
34 | <h3>RETURN VALUES</h3> | |
35 | <dl> | |
36 | <p> | |
37 | <dt> <strong>TRUE</strong> | |
38 | <dd> | |
39 | The message was handled and the appropriate function was called. | |
40 | <p> | |
41 | <dt> <strong>FALSE</strong> | |
42 | <dd> | |
43 | The message did not apply to the alarm mechanism and no other action | |
44 | was taken. | |
