API Functions

VSCMD_CreateMediaClass

 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 value is 

VSE_NONE

, the client must 

query the global error code (

VSG_Error

) to 

determine where the error occurred.

Value to be put in 

USER_FIELD

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

.

VSID_VERSION_NUMBER 
(VST_VERSION_NUMBER)

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