API Functions

VSCMD_Export

 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.

•

VSE_ERR_BADHANDLE

 - Specified handle was not a valid 

command handle.

•

VSE_ERR_NULLHANDLE

 - Specified handle was a null 

pointer.

-

If the object code’s value is 

VSE_VOLSERV

, the error 

occurred in VolServ, and the client uses 

VST_ERROR_NUMCODE

 to identify the specific error. 

-

If the object code’s value is not 

VSE_VOLSERV

 and is 

not 

VSE_NONE

, the error occurred in the API, and the 

client uses 

VST_ERROR_CODE

 to identify the 

specific error.

•

VSE_ERR_BADFIELD

 - An invalid parameter was 

specified.
