* Modification Log:
|
|
* -----------------
|
|
* .01 11-11-91 jba Moved set of alarm stat and sevr to macros
|
|
* .02 12-02-91 jba Added cmd control to io-interrupt processing
|
|
* .03 12-12-91 jba Set cmd to zero in io-interrupt processing
|
|
* .04 02-05-92 jba Changed function arguments from paddr to precord
|
|
* .05 02-28-92 jba Changed callback handling, ANSI C changes
|
|
* .06 03-13-92 jba ANSI C changes
|
|
* .07 04-10-92 jba pact now used to test for asyn processing, not return value
|
|
* .08 04-18-92 jba removed process from init_record parms
|
|
* .09 09-01-93 joh expects EPICS standard status
