NAME
irServiceDataSuspend, irCallDataSuspend, irCallDataResume,
irSetServiceEventBuf, irGetServiceEventBuf - manipulate call
and service data
SYNOPSIS
#include <irapi.h>
int irCallDataSuspend (channel_id cid);
int irServiceDataSuspend (channel_id cid);
int irCallDataResume (channel_id cid);
int irSetServiceEventBuf (channel_id cid, int event_number,
void *src, size_t size);
int irGetServiceEventBuf (channel_id cid, int event_number,
void *dest, size_t size);
DESCRIPTION
These functions manage the IRAPI call data record that is
stored for the cid owned by the application. Call and ser-
vice data are normally initialized and posted (written to
the Call Data Handler (CDH)) for the application automati-
cally by the IRAPI at appropriate times.
The following table shows when per channel call data is ini-
tialized and written for the CALL and SERVICE data. Note
that EVENTS data is initialized and written in synchrony
with SERVICE.

1. CALL Data: This part of the record consists of call
specific data such as the channel number on which the
call was handled and the start time and end time of the
call. When CALL Data are initialized, the channel
number is set and the start time is set to the current
system time. The end time is set when the CALL Data are
written.
2. SERVICE Data: Since many different applications ("ser-
vices") may run during a call, there may be more than
one SERVICE Data record per CALL Data record. SERVICE
Data consist of service specific information such as the
service name, the start time and end time of the ser-
vice, and the service EVENTS data (described below).
When SERVICE Data are initialized, the service name is
set from the value of IRP_SERVICE_NAME parameter, the
start time is set to the current system time, and the
service EVENTS data are set to null. The end time is
set when the SERVICE Data are written.
3. EVENTS Data: The service EVENTS data are a subset of the
SERVICE data described above. EVENTS data are stored in
a IRD_MAX_CDSEV word (integer) array totalling
sizeof(int) * IRD_MAX_CDSEV bytes in length. This array
may contain event data in the form of integers or
strings. Each data item must begin on a word (4-byte
integer) boundry. Each item stored in the EVENTS data
buffer is assigned an <event_number> between 0 and
IRD_MAX_CDSEV-1 (corresponding to its index in the
buffer) and an <event_name> (an alphanumeric label for
the event to be used in Call Data Reports). The struc-
ture of the IRD_MAX_CDSEV word sized block (event IDs,
names, and data types) is described to the call data
subsystem through the <service_name>.D file.
<service_name> is taken from the IRP_SERVICE_NAME param-
eter. This file must exist in the /vs/trans directory
for both writing and reading the EVENTS data. If it
does not exist, the EVENTS data will be dropped.
event (each consecutive <event_number> represents 4
bytes of space).
The function irServiceDataSuspend will inhibit writing any
SERVICE and EVENTS data for the current application to the
CDH when irDeinit(3IRAPI), irExec(3IRAPI) or
irReturn(3IRAPI) is called.
The function irCallDataSuspend Will inhibit writing any CALL
or SERVICE and EVENTS data for the current application to
the CDH when irDeinit(4IRAPI), irExec(4IRAPI), or
irReturn(4IRAPI) are called. Note: Writing CALL data on
irDeinit() signals the CDH that the call is complete. An
application which uses irCallDataSuspend() when other appli-
cations run during the same call have not may cause SERVICE
and EVENTS data on subsequent calls to be merged with that
generated on the current call.
The function irCallDataResume will reinitialize CALL and
SERVICE data (setting the start time for each to the current
time) for the current application. Any EVENTS data set by
the application with irSetServiceEventBuf() before calling
this function remains unchanged.
The function irSetServiceEventBuf sets call data service
event number event_number to src, where size is the size of
the data pointed to by src in bytes. The function
irGetServiceEventBuf copys into the area pointed to by dest
the data for event_number , where size is the size of the
data to be copied in bytes. A valid event_number is simply
an integer ranging from 0 to IRD_MAX_CDSEV-1 that may have
arbitrary meanings for end-user applications. (See the dis-
cussion of the <service_name>.D file above.)
RETURN VALUE
IRR_OK is returned if the request is successful.
IRR_FAIL is returned if an error occurs.
