DL_RESET_IND Primitive


Indicates a data link service (DLS) connection has been reset.


The primitive consists of one M_PROTO message block, which contains the following structure:

typedef struct 
   ulong dl_primitive;
   ulong dl_originator;
   ulong dl_reason;
} dl_disconnect_ind_t;


The DL_RESET_IND primitive informs the DLS user that either the remote DLS user is resynchronizing the data link connection, or the DLS provider is reporting loss of data from which it can not recover. The primitive indicates the reason for the reset.

Note: This primitive applies to connection mode.


dl_primitive Specifies the DL_RESET_IND primitive.
dl_originator Specifies whether the reset was originated by the DLS user or DLS provider. The values are DL_USER or DL_PROVIDER, respectively.
dl_reason Indicates one of the following reasons for the reset:
DL_RESET_FLOW_CONTROL Indicates flow control congestion.
DL_RESET_LINK_ERROR Indicates the occurrence of a data link error.
DL_RESET_RESYNCH Indicates a request for resynchronization of a data link connection.


Valid The primitive is valid in the DL_DATAXFER state.
New The resulting state is DL_PROV_RESET_PENDING.


The DLS user should issue a DL_RESET_RES primitive to continue the resynchronization procedure.

Implementation Specifics

This primitive is part of Base Operating System (BOS) Runtime.
