DL_SYSERR
A system error has occurred and the UNIX system error is indicated
in the DL_ERROR_ACK.
DL_DETACH_REQ
Requests the DLS provider to disassociate a physical point of attachment
(PPA) with a stream.
The message consists of one M_PROTO message block, which contains
the following structure.
Format
typedef struct {
ulong dl_primitive;
} dl_detach_req_t;
Parameters
dl_primitive
DL_DETACH_REQ
State
The message is valid in state DL_UNBOUND.
New State
The resulting state is DL_DETACH_PENDING.
Response
If the detach request is successful, DL_OK_ACK is sent to the DLS user
resulting in state DL_UNATTACHED.
If the request fails, DL_ERROR_ACK is returned and the resulting state
is unchanged.
