Hi Euan,

That should be no problem. Of course then your database becomes

incompatible with "normal" versions of EPICS base so that you need to be

careful when upgrading your EPICS version or exporting your database to

other EPICS users. But since the effect of the modification is limited

to the IOCs, it is compatible with any EPICS version on other IOCs and

any client software.

The maximum number is 32768 because the EVNT field is a DBF_SHORT.

You may also be interested in my code to use strings instead of numbers

for soft events from the codeathlon 2010. Unfortunately it didn't make

it into 3.14.12.

Best regards,
Dirk

Hi,

In the EPICS applications developers guide the following is presented:

 17.4.2 Event Scanning

Event scanning is built around the following definitions:

#define MAX_EVENTS 256
typedef struct event_scan_list {
    CALLBACK        callback;
    scan_list       scan_list;
} event_scan_list;
static event_scan_list
*pevent_list[NUM_CALLBACK_PRIORITIES][MAX_EVENTS];

Is it possible to increase the MAX_NUMBER definition to enable more event numbers to be used in a linux soft IOC?

cheers,

Euan.
