API Functions

601355 Rev A

VS_Notify_Listen

 listens for MediaClass callbacks from 

VolServ.

Client registers a notify dispatch routine with the API using 
either the 

VS_Global_SetFields

 or the 

VS_Notify_SetFields

 function. Client is then responsible 

for putting the API into a “listening” state by calling 

VS_Notify_Listen

. 

VS_Notify_Listen

 terminates 

either after receiving a MediaClass callback and notifying the 
client’s notify dispatch routine or after timing out.
