API Functions

601355 Rev A

VSCMD_ArchiveQuery

 returns:

•

VSE_TRUE

-

Successful execution if the API is operating in 
synchronous mode.

-

Good initial status received if the API is operating in 
asynchronous mode.

•

VSE_FALSE

 - The command failed. A return code of 

VSE_FALSE

 (which is 0) means the command failed. 

-

To determine where the error occurred, and what the 
error was, the client queries the command’s error 
handle (with 

VS_Error_GetFields

) to retrieve 

the error handle’s object code. 

-

If the object code’s value is 

VSE_NONE

, the client 

must query the global error code (

VSG_Error

) to 

determine where the error occurred.

VSID_TIMEOUT_VALUE (VST_TIME_OUT)

Amount of time (in seconds) the API software 
waits for status from VolServ before returning 
a timeout to the client software for this 
request. The default time-out value is 120 
seconds.

VSID_USER_FIELD (VST_USER_FIELD)

Value to be put in 

USER_FIELD

 for this 

ArchiveQuery command request. 

USER_FIELD

 is 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 this request. 
Neither the API software nor VolServ uses 

USER_FIELD.
