Intel IP Media Server ユーザーズマニュアル

42

The TSUsrEvent structure is used by the demo modules to return event processing results to the 
event router. 

The TSUserEvt structure is defined as follows:

typedef struct
{
  int         event;
  TDeviceType destination;
  int         lineDevice;
  long        xmitSlot;
  long        neighborDevice;
  char        dialString[MAX_STRING_LENGTH]}
TSUserEvent;

The fields of the TSUserEvt structure are described as follows:

event 

the name of a user-defined event, such as USR_CONNECTED, USR_SENDFAX, etc.

destination 

the name of the module that this event is destined for. Possible vavues are IP, VOICE, FAX, or 
NONE. 

lineDevice 

the device handle in this module. It will be later used by the Event Router as an index to find its 
counterpart in the destination module.

xmitSlot 

an integer that normally indicates a time slot number

neighborDevice 

the neighbor device handle

dialString 

a char string that is normally filled with a DTMF dialing string

This section describes a typical scenario for sending a fax, which involves all the IP Media Server 
demo modules.

When an incoming call is received by the server, the IP module answers the call until the call is 
connected.
