SYNOPSIS

The format of the message is one M_PCPROTO message block. The format of the M_PCPROTO message block is as follows:

    t_scalar_t   PRIM_type;      /* Always T_INFO_REQ */
};

DESCRIPTION

This primitive requests the transport provider to return the sizes of all relevant protocol parameters, plus the current state of the provider.

Note that the T_INFO_REQ and T_INFO_ACK(7) primitives have no effect on the state of the transport provider and do not appear in the state tables.

PARAMETERS

-: Successful: Acknowledgment of the primitive via the T_INFO_ACK(7).
-: Non-fatal errors: There are no errors associated with this primitive.

MODES

Both connection-mode and connectionless-mode.
