6.9. NONCRN_BLK

The NONCRN_BLK structure contains information related to a GLOBAL or NULL call reference number (CRN). The messages are sent to the network using the SndNonCallMsg( ) function.

The structure is defined as follows:

#define MAXLEN_IEDATA  254  
typedef struct   
  {  
    char    sapi;     
    char    ces;  
    short   length;  
    char  data[MAXLEN_IEDATA];  
  } NONCRN_BLK, *NONCRN_BLK_PTR;
