API Functions

2-1075

VSCMD_Unlock

 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 request failed. A return code of 

VSE_FALSE

 (which is 0) means the request failed. 

-

To determine where the error occurred, and what the 
error was, the client queries the request’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)

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

VSID_USER_FIELD (VST_USER_FIELD)

The value to put in 

USER_FIELD

 for this 

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

.
