SccpInitGenCfg

Initializes an SCCP general configuration buffer to default values that can be passed to SccpSetGenCfg.

SCCP_STATUS SccpInitGenCfg ( SccpGenCfg *pCfg)

Return values

Details

Prior to calling SccpSetGenCfg to send the configuration to the SCCP layer, the application can change the default values within the specified range for any fields other than those denoted as internal or unused.

The SCCPGenCfg structure contains the following fields:

Default values for the SccpGenCfg structure that can be overridden by the calling application are listed in the following table.

Note: SccpGenCfg structure members not listed in the following table are either unused or for internal use only. These fields are set to correct values by SccpInitGenCfg and must not be overridden by the application.

All values listed in the following table can be modified on the first call to SccpSetGenCfg. On subsequent calls to SccpSetGenCfg, only parameters listed in bold can be modified. Those fields not in bold are ignored on subsequent calls.
