- modification history
- --------------------
- 01f,23jul98,dbt if the agent is already connected to a target server when we
- receive a new connect request, call wdbTargetDisconnect() to
- remove all old eventpoints.
- 01e,12feb98,dbt replaced wdbEvtLib.h include with wdbEvtptLib.h. Remove
- dynamically loaded services when we connect to a new target
- server.
- 01d,05jul96,p_m added WDB_TARGET_MODE_GET (SPR# 6200).
- 01c,07jun95,ms remove all eventpoints during WDB_TARGET_DISCONNECT.
- 01b,02jun95,ms Added wdbTargetIsConnected().
- 01a,21sep94,ms written.

- DESCPRIPTION
- This library contains the session management services:
- WDB_TARGET_CONNECT connect to agent
- WDB_TARGET_DISCONNECT disconnect from agent
- WDB_TARGET_MODE_SET change agent mode (system vs tasking)
- WDB_TARGET_MODE_GET return agent mode
- WDB_TARGET_PING test the connection.
