Outline

Stop alarm handler operation.

C format

 ER      stp_alm (ID almid);

 ER      istp_alm (ID almid);

Parameter(s)

I/O	Parameter	Description
I	ID almid;	ID number of the alarm handler.

Explanation

This service call moves the alarm handler specified by parameter almid from the operational state (STA state) to non-operational state (STP state).

As a result, the target alarm handler is excluded from activation targets of the RI600V4 until issuance of sta_alm or ista_alm.

Note This service call does not perform queuing of stop requests. If the target alarm handler has been moved to the non-operational state (STP state), therefore, no processing is performed but it is not handled as an error.

Return value

Macro	Value	Description
E_OK	0	Normal completion.
E_ID	-18	Invalid ID number. - almid < 0 - almid > VTMAX_ALH
E_CTX	-25	Context error. - This service call was issued in the CPU locked state. - This service call was issued in the status "PSW.IPL > kernel interrupt mask level". Note When the istp_alm is issued from task or the stp_alm is issued from non-task, the context error is not detected and normal operation of the system is not guaranteed.
