DL_INFO_REQ Primitive


Requests information about the Data Link Provider Interface (DLPI) stream.


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

typedef struct 
   ulong dl_primitive;
} dl_info_req_t;

This structure is defined in /usr/include/sys/dlpi.h.


The DL_INFO_REQ primitive requests information from the data link service (DLS) provider about the DLPI stream. This information includes a set of provider-specific parameters, as well as the current state of the interface.


dl_primitive Conveys the DL_INFO_REQ primitive.


Valid The primitive is valid in any state in which a local acknowledgment is not pending.
New The resulting state is unchanged.


The DLS provider responds to the information request with a DL_INFO_ACK primitive.

Implementation Specifics

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