X25_FLG_D_BIT Indicates that the call uses D-bit procedures.
X25_FLG_LINK_NAME Indicates that the link_name field is used.
X25_FLG_CALLED_ADDR Indicates that the called_addr field is used.
X25_FLG_CALLING_ADDR Indicates that the calling_addr field is used.
X25_FLG_CB_FAC Indicates that the cb_fac field is used.
X25_FLG_USER_DATA Indicates that the user_data field is used.


flags Notification to the API that the associated field has been used.
link_name Name of the X.25 port used for an incoming call.
This is set to null on received packets.
called_addr Pointer to the network user address (NUA) of the called data terminal equipment (DTE). The address is given in ASCIIZ format.
calling_addr Pointer to the NUA of the calling DTE. The address is given in ASCIIZ format.
cb_fac Pointer to the facilities information in the cb_fac_struct structure.
user_data_len Field length for call user data (CUD).
