Introduced error status values for epicsTime routines. The epicsTimeERROR identifier no longer exists, so code that uses it will no longer compile (deliberately). Replace all uses of it with a specific error status value.

<h3>epicsTime API return status</h3>
|
|
|
|
<p>The epicsTime routines that used to return epicsTimeERROR now return a specific
|
|
S_time_ status value, allowing the caller to discover the reason for any failure.
|
|
The identifier <tt>epicsTimeERROR</tt> is no longer defined, so any references to
|
|
it in source code will no longer compile. The identifier epicsTimeOK still exists
|
|
and has the value 0 as before, so most code that uses these APIs can be changed in
|
|
a way that is backwards-compatible with the previous return status.</p>
|
|
|
|
<h3>Callback subsystem API</h3>
|
|
|
|
<p>Added a new macro <tt>callbackGetPriority(prio, callback)</tt> to the
|
|
callback.h header and removed the need for dbScan.c to reach into the internals
|
|
of its CALLBACK objects.</p>
