Global parameters are a group of parameters that are used by 
the API for all VolServ requests. Most of these are sent to 
VolServ, but some serve as control information for the API. The 
following table describe these parameters. 

VSID_CLIENT_DISPATCH

Pointer to the dispatch function for all commands.

VSID_ENTERPRISE_ID 

Identifier of the enterprise, if any, to receive intermediate and 
final status on every command request.

VSID_NOTIFY_DISPATCH 

Pointer to the dispatch function used for notification 
(MediaClass callback) processing.

VSID_PRIORITY

(defaults to 15)

Execution priority assigned to every command request.

Values range from 1 (highest) to 32 (lowest).

VSID_RETRY_LIMIT

Number of times the API software is to retry for command 
status from VolServ before returning a time-out to the client 
software.

Total length of time the API software waits for a command 
status from VolServ is (

VSID_RETRY_LIMIT

 plus1) multiplied 

by the 

VSID_TIMEOUT_VALUE

.

VSID_RETRY_LIMIT

 is not applicable when the API software 

executes in asynchronous mode.

VSID_STATUS_WAIT_FLAG

Status wait flag for all commands. This flag controls whether 
the API operates in synchronous or asynchronous mode. If its 
value TRUE, the API waits for status (operate in synchronous 
mode.) If its value is FALSE, the API operates in asynchronous 
mode.

VSID_TIMEOUT_VALUE 

Amount of time, in seconds, VolServ waits for status before 
timing-out to the client software for this request.

VSID_USER_FIELD

A 16-character field provided for user information. Information 
entered in this field is echoed back to the user in every status 
message returned for each command. Neither the API 
software nor VolServ uses 

USER_FIELD

.
