Processing during ADSM Server Initialization

Ensure that the external media management program cooperates with the ADSM server during the server's initialization. For each external library defined to the ADSM server, the following must occur during server initialization:

1. The ADSM server loads the external program (execl) in a newly created process and creates pipes to the external program.

2. The server sends an initialization request description string, in text form, into the standard input (stdin) stream of the external program. The server waits for the response.

3. When the external process completes the request, the process must write an initialization response string, in text form, into its standard output (stdout) stream.

4. The ADSM server closes the pipes.

5. When the agent detects that the pipes are closed, it performs any necessary cleanup and calls the stdlib exit routine.
