Subject: The 'syd' directory
From: Andy Foster <[email protected]>

Thank-you to all those who answered and sent ftp sites for
the libraries required to build the Tcl/Tk - CA interface.

In building 'extensions', I noticed that there are two copies
of the directory 'syd'. One under 'ar' and one under 'opi'.
In doing a diff on the two directories, I had code differences
in 'sydSubrCA.c'. The version under 'opi' has the extra lines:

> /*	sydSubrCA.c,v 1.2 1995/04/28 01:10:31 epics Exp
289a290,299
>     if(pSChan->elCount < 1){
> 	(void)printf(
>                 "sydCAFunc: the element requested, %s, has a count(NELM) of 0\n",
> 		pSChan->name);
>  	(void)printf(
> 		"Cannot set up communication (CA) with 0 count\n");  
> 	ca_clear_channel(pCh);
> 	retStat = S_syd_ERROR;
> 	return retStat;
>     }

My questions are:
Should there be just one copy of 'syd' for all extensions?
  if yes, where should it be located?
  if no, should each be built into a library with a different name?
Which of my versions of 'sydSubrCA.c' is current?

Thanks,

Andy
