DLPI Primitives
Connection-mode Service Primitives
Format
typedef struct {
u_long dl_primitive;
} dl_hp_info_req_t;
Parameters
dl_primitive
DL_HP_INFO_REQ
State
The message is valid in the states DL_IDLE, DL_DATAXFER,
DL_OUTCON_PENDING, DL_INCON_PENDING,
DL_USER_RESET_PENDING, and DL_PROV_RESET_PENDING.
New State
The resulting state is unchanged.
Response
If the primitive is issued from a valid state, the DLS provider responds
with a DL_HP_INFO_ACK. Otherwise a DL_ERROR_ACK is returned.
Reasons for Failure
DL_OUTSTATE
Primitive was issued from an invalid state.
DL_HP_INFO_ACK
This message is sent in response to a DL_HP_INFO_REQ; it conveys
information on the state of the connection on a DLPI stream.
