stp_cyc

istp_cyc

Outline

Stop cyclic handler operation.

C format

 ER      stp_cyc (ID cycid);

 ER      istp_cyc (ID cycid);

Parameter(s)

I/O	Parameter	Description
I	ID cycid;	ID number of the cyclic handler.

Explanation

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

As a result, the target cyclic handler is excluded from activation targets of the RI600PX until issuance of sta_cyc or ista_cyc.

Note This service call does not perform queuing of stop requests. If the target cyclic 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. - cycid < 0 - cycid > VTMAX_CYH
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_cyc is issued from task or the stp_cyc is issued from non-task, the context error is not detected and normal operation of the system is not guaranteed.
E_NOEXS	-42	Non-existent object. - The cyclic handler specified by cycid does not exist.
