Changes between 3.14.9 and 3.14.10

+

IOC Support on 64-bit archs

+ +

A fairly significant number of changes have been that were necessary to allow +the IOC code to run properly on 64-bit CPU architectures where a long +is 64 bits wide. This was not as simple as replacing every instance of the +typename long with epicsInt32 because that would have broken a +lot of external code unnecessarily. The generated record.h file now uses the +typenames from epicsTypes.h to declare record fields, thus field sizes are the +same on both 32- and 64-bit platforms (on 64-bit, a DBF_LONG does +not map to long but to int). This change does not +affect status return values, which are still implemented using the native +long type for the platform.

+ +

Conversion of empty strings to character types

+ +

While changing the conversion routines in db/dbConvert.c and +db/dbFastLinkConv.c to support 64-bit architectures as described above, it was +noticed that an empty string converts to the value 0 for all types other than +DBF_CHAR and DBF_UCHAR where it converts to the ASCII +character '0', value 0x30. Since these types are usually used for +storing small integers or boolean values rather than ASCII characters, it was +decided that this conversion is wrong so it has been changed to match the other +nmeric conversions.

+ +

epicsShareAPI deprecated inside IOC

+ +

APIs that are intended for use inside the IOC, the epicsShareAPI +attribute is slowly being removed. This keyword is only used on MS Windows +where it indicates to the compiler that the function should use Pascal calling +conventions rather than C ones, and was necessary to be able to call such +functions from MS Visual Basic. APIs for use by client code (CA and libCom) +will generally retain the attribute if they already had it.

+ +

Record types ANSIfied

+ +

Thanks to John Hammonds at the EPICS Codeathon, the record type +implementations have been converted from K&R to ANSI C prototypes.
