NAME

DL_SUBS_BIND_REQ (dl_subs_bind_req_t) - requests the DLS provider bind a subsequent DLSAP to the stream. The DLS user must identify the address of the subsequent DLSAP to be bound to the stream.

SYNOPSIS

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

typedef struct {
    t_uscalar_t  dl_primitive;
    t_uscalar_t  dl_subs_sap_offset;
    t_uscalar_t  dl_subs_sap_length;
    t_uscalar_t  dl_subs_bind_class;
} dl_subs_bind_req_t;

PARAMETERS

dl_primitive

conveys DL_SUBS_BIND_REQ.

dl_subs_sap_offset

conveys the offset of the DLSAP from the beginning of the M_PROTO block.

dl_subs_sap_length

conveys the length of the specified DLSAP.

dl_subs_bind_class

specifies either peer or hierarchical addressing:

DL_PEER_BIND

specifies peer addressing. The DLSAP specified is used in lieu of the DLSAP bound in the BIND request.

DL_HIERARCHICAL_BIND

specifies hierarchical addressing. The DLSAP specified is used in addition to the DLSAP specified using the BIND request.

STATE

The message is valid in state DL_IDLE.

NEW STATE

The resulting state is DL_SUBS_BIND_PND.

RESPONSE

If the subsequent bind request is successful, DL_SUBS_BIND_ACK is sent to the DLS user resulting in state DL_IDLE. If the request fails, message DL_ERROR_ACK is returned and the resulting state is unchanged.

ERRORS

DL_ACCESS

The DLS user did not have proper permission to use the requested DLSAP address.

DL_BADADDR

The DLSAP address information was invalid or was in an incorrect format.

DL_OUTSTATE

The primitive was issued from an invalid state.

DL_SYSERR

A System error has occurred and the UNIX system error is indicated in the DL_ERROR_ACK.

DL_TOOMANY

Limit exceeded on the maximum number of DLSAPs per stream.

DL_UNSUPPORTED

Requested addressing class not supported.
