** SOURCE FILE NAME: clisnapnew.c 
**
** SAMPLE: Capture a snapshot at the client level
**          
**         This sample creates an instance attachment, and calls functions  
**         in utilsnap.c to capture an application-level snapshot and print
**         the monitor data. Monitor data from the application-level
**         logical data groups is unavailable if no applications are
**         connected to the database being monitored.
**
**         In order to access application-level monitor data, you must
**         connect to the relevant database before you run this sample.
**
** DB2 APIs USED:
**         db2GetSnapshot -- Get Snapshot
**
** STRUCTURES USED:
**         sqlma
**
**
