DLPI Primitives
Local Management Primitives
Chapter 2
93
Format
The message consists of one M_PCPROTO message block, which
contains the following structure:
typedef struct {
ulong
dl_primitive;
ulong
dl_error_primitive;
ulong
dl_errno;
ulong
dl_unix_errno;
} dl_error_ack_t;_
Parameters
dl_primitive
DL_ERROR_ACK
dl_error_primitive
primitive that is in error.
dl_errno
DLPI error code associated with the failure.
dl_unix_errno
UNIX system error code associated with the failure. This value
should be non-zero only when dl_errno is set to DL_SYSERR. It is
used to report UNIX system failures that prevent the processing of a
given request or response.
State
The message is valid in every state where an acknowledgement or
confirmation of a previous request or response is pending.
New State
The resulting state is that from which the acknowledged request or
response was generated.
Optional Primitives to Perform Essential
Management Functions
This section describes optional primitives. Some of these primitives may
not be supported by the DLS provider.
