typedef struct | { |
ulong | dl_primitive; |
ulong | dl_subs_sap_offset; |
ulong | dl_subs_sap_length; |
}dl_subs_unbind_req_t;
Parameters
dl_primitive
DL_SUBS_UNBIND_REQ
dl_subs_sap_offset
offset of the DLSAP from the beginning of the M_PROTO block.
dl_subs_sap_length
length of the specified DLSAP.
State
The message is valid in state DL_IDLE.
