Leif Hedstrom updated TS-977:

                   3.1.3

> int RecGetRecordInt(const char *name, RecInt * rec_int, bool lock = true);
> //-------------------------------------------------------------------------
> // RecGetRecordXXX
> //-------------------------------------------------------------------------
> int
> RecGetRecordInt(const char *name, RecInt *rec_int, bool lock)
> {
>   int err;
>   RecData data;
>   if ((err = RecGetRecord_Xmalloc(name, RECD_INT, &data, lock)) == REC_ERR_OKAY)
>     *rec_int = data.rec_int;
>   return err;
> }
> {code}
> and there is something heavy used:
> {code}
> //-------------------------------------------------------------------------
> // Backwards Compatibility Items (REC_ prefix)
> //-------------------------------------------------------------------------
> #define REC_ReadConfigInt32(_var,_config_var_name) do { \
>   RecInt tmp = 0; \
>   RecGetRecordInt(_config_var_name, (RecInt*) &tmp); \
>   _var = (int32_t)tmp; \
> } while (0)
> #define REC_ReadConfigInteger(_var,_config_var_name) do { \
>   RecInt tmp = 0; \
>   RecGetRecordInt(_config_var_name, &tmp); \
>   _var = tmp; \
> } while (0)
> {code}
> and a real case, the REC_ReadConfigInteger is renamed to IOCORE_ReadConfigInteger:
> {code}
> RecInt cache_config_threads_per_disk = 12;
> #define IOCORE_ReadConfigInteger            REC_ReadConfigInteger
>   IOCORE_ReadConfigInteger(cache_config_threads_per_disk, "proxy.config.cache.threads_per_disk");
> {code}
> my question is, why it is so complex in all these renaming? why not just:
> {code}
> RecGetRecordInt("proxy.config.cache.threads_per_disk", &cache_config_threads_per_disk);
> {code}
> brief talk with Leif, we may need to cleanup the use of REC_*. make it a small task here
