The API must be initialized with a call to 

VS_Initialize

 

before this function can be executed.

The total length of time the API software waits for a command 
status in synchronous mode from VolServ is 
(

VSID_RETRY_LIMIT

 plus 1) multiplied by 

VSID_TIMEOUT_VALUE

.

If the 

VSID_ENTERPRISE_ID

 parameter is set to any value 

other than zero, the API cannot receive status for this request.

When the API software is operating in asynchronous mode, 
client software must call 

VS_Select

 to receive intermediate 

and final status on command requests submitted through the 
API interface to the VolServ system.

VolServ generates intermediate status in response to an Archive 
Query request if:
