The DLINK data structure contains information about the data link information block. The DLINK structure is passed for the cc_GetDLinkCfg( ), cc_SetDLinkCfg( ), cc_GetDLinkState( ) and cc_SetDLinkState( ) functions.

The DLINK structure is used in the following structures:

• SPID_BLK, see Section 6.11. SPID_BLK
• TERM_BLK, see Section 6.12. TERM_BLK
• TERM_NACK_BLK, see Section 6.13. TERM_NACK_BLK
• USPID_BLK, see Section 6.15. USPID_BLK

The DLINK structure is defined as follows:

typedef   struct     
{  
    char  sapi;  
    char  ces;  
}  DLINK,   *DLINK_PTR;
