API Functions

601355 Rev A

VSCMD_ModifyMediaClass

 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. 

VSID_USER_FIELD (VST_USER_FIELD)

A value to put in 

USER_FIELD

 for Modify 

Media Class commands. 

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 Modify Media Class 
commands. Neither the API software nor 
VolServ uses 

USER_FIELD

.

VSID_VERSION_NUMBER 
(VST_VERSION_NUMBER)

The RPC version number of the client process 
to receive callbacks generated for this 
MediaClass group. 

VSID_VERSION_NUMBER

 

is required if 

VSID_CLASS_RPC_OPTION

 is 

set to 

VSE_CLASS_RPC_ENTERPRISE

. 

Otherwise, 

VSID_VERSION_NUMBER

 is not 

applicable.
