Hi All,

I need to change the max. size of group names  in Spread 3.17.3 on WinXP( cygwin ) ?
How should I go about it ?.

I tried foll. changes as suggested on previous post(s):-


#define  MAX_GROUP_NAME  52
#define         MAX_PRIVATE_NAME        30 /* largest possible size of private_name field of SP_connect() */
#define         MAX_PROC_NAME           20 /* largest possible size of process name of daemon */


#define  MAX_PRIVATE_NAME  30     /* not including the null, look for it if changed */

I connect to daemon using Java client on WinXP and I get foll. exception after the modification:-

SpreadException: spread.SpreadException: read(): java.net.SocketException: Connection reset
Everthing works fine if I build from source with default group name size of 32. 
Has anyone encountered this before ? Any help would be appreciated.
