Requests that an active data link be disconnected.
The primitive consists of one
M_PROTO message block, which contains the following
The DL_DISCONNECT_REQ primitive requests the data link service (DLS) provider to disconnect an active data link connection or one that was in the process of activation. The DL_DISCONNECT_REQ primitive can be sent in response to a previously issued DL_CONNECT_IND or DL_CONNECT_REQ primitive. If an incoming DL_CONNECT_IND primitive is being refused, the correlation number associated with that connect indication must be supplied. The message indicates the reason for the disconnect.
Note: This primitive applies to connection mode.
|dl_primitive||Specifies the DL_DISCONNECT_REQ primitive.|
|dl_reason||Indicates one of the following reasons for the disconnect:
|dl_correlation||Specifies one of the following values:
|Valid||The primitive is valid in any of the following states:|
|Successful||The DL_OK_ACK primitive is sent to the DLS user resulting in the DL_IDLE state.|
|Unsuccessful||The DL_ERROR_ACK primitive is returned, and the resulting state is unchanged.|
|DL_BADCORR||Indicates the correlation number specified in this primitive does not correspond to a pending connect indication.|
|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.|
This primitive is part of Base Operating System (BOS) Runtime.
