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.
Valid | The primitive is valid in the DL_IDLE state. |
New | The resulting state is DL_SUBS_UNBIND_PND. |
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. |
This primitive is part of Base Operating System (BOS) Runtime.
The DL_OK_ACK primitive, DL_ERROR_ACK primitive, DL_SUBS_BIND_REQ primitive.
