ETRIGGER

Draft MDC Standard

8.2.12 ETrigger

ETR[IGGER] postcond SP especref

    especref::=

expr V ^$W[INDOW] ( expec ) [ : einforef ]
expr V ^$J[OB] ( erspec )


    einforef::=
See X11.6
    espec::=
See X11.6
    erspec::= processid , expr1 V "EVENT", expr2 evclass expr3 V evid
    evid::= expr

Note that the definitions of espec and einforef are copied from X11.6, the MWAPI. Note also that the range of values allowed for evid depends on the value of evclass, and may be implementation-specific.

ETrigger causes an event to occur, though use of a processid other than the current job’s own processid may be restricted by the implementation. This restricted use does not generate an error, but will not generate an event. Restrictions (if any) must be specified in the implementation’s conformance statement.

If the use is not restricted and the specified event is enabled for either synchronous or asynchronous event processing, the event processing for it will occur subsequently. The event that occurs is specified by evclass and evid. If evid does not specify a valid event, an error condition occurs with an ecode = "M103".

If evclass evaluates to "IPC" and evid is not the current job’s processid an error condition occurs with an ecode = "M104".
