VS_Select

 calls fail if 

VS_Initialize

 has not been 

invoked.

VS_Select

 is used only when the API is operating in 

asynchronous mode. Therefore, clients that use synchronous 
processing do not use the 

VS_Select

 

routine.

The VolServ API uses the client dispatch routine identification 
information, set with the 

VS_Global_SetDefaults

 function 

or with the command default function, to determine which 
routine to notify when intermediate and final command status is 
received.

The total amount time the API waits for status is 

VSID_TIMEOUT_VALUE

.

VS_Select

 returns error codes instead of the normal 

VST_BOOLEAN

 values (

VSE_TRUE

, 

VSE_FALSE

). This 

simplifies client code when performing asynchronous 
processing. Client can use the “switch” statement on the return 
code directly from the routine without having to retrieve error 
codes.
