Requests that the data link service (DLS) provider unbind the data link service access point (DLSAP) that was bound by a previous DL_SUBS_BIND_REQ primitive from this stream.
The message consists of one M_PROTO message block, which contains the following structure:
typedef struct
{
ulong dl_primitive;
ulong dl_subs_sap_length;
ulong dl_subs_sap_offset;
} dl_subs_unbind_req_t;
This structure is defined in /usr/include/sys/dlpi.h.
The DL_SUBS_UNBIND_REQ primitive requests that the DLS provider unbind the DLSAP that was bound by a previous DL_SUBS_BIND_REQ primitive from this stream.
| Item | Description |
|---|---|
| dl_primitive | Specifies the DL_SUBS_UNBIND_REQ primitive. |
| dl_subs_sap_length | Specifies the length of the specified DLSAP. |
| dl_subs_sap_offset | Indicates where the DLSAP begins. The value of this parameter is the offset from the beginning of the M_PROTO message block. |
| Item | Description |
|---|---|
| Valid | The primitive is valid in the DL_IDLE state. |
| New | The resulting state is DL_SUBS_UNBIND_PND. |
| Item | Description |
|---|---|
| Successful | The DL_OK_ACK primitive is sent to the DLS user. The resulting state is DL_IDLE. |
| Unsuccessful | The DL_ERROR_ACK primitive is returned, and the resulting state is unchanged. |
| Item | Description |
|---|---|
| DL_BADADDR | Indicates the DLSAP address information is invalid or is in an incorrect format. |
| DL_OUTSTATE | Indicates the primitive was issued from an invalid state. |
| DL_SYSERR | Indicates a system error occurred. The system error is indicated in the DL_ERROR_ACK primitive. |
