5.4. DV_TPT: Termination Parameter Table

The DV_TPT data structure contains parameters for the Termination Parameter Table.

5.4.1. DV_TPT Overview

The DV_TPT structure is in the Standard Runtime Library (srllib.h) and is used to set multitasking I/O function termination conditions. To specify multiple termination conditions for a function, you can use a set of DV_TPT structures configured as a linked list, an array, or a combined linked list and array, with each DV_TPT specifying a terminating condition. The first termination condition that is met will terminate the I/O function.

5.4.2. DV_TPT Definition

The typedef for the structure is as follows:

    typedef struct DV_TPT {

       unsigned short   tp_type;             /* Flags describing this entry */

       unsigned short   tp_termno;           /* Termination Parameter number */

       unsigned short   tp_length;           /* Length of terminator */

       unsigned short   tp_flags;            /* Parameter attribute flag */

       unsigned short   tp_data;             /* Optional additional data */

       unsigned short   rfu;                 /* Reserved                 */

       DV_TPT           *tp_nextp;           /* Pointer to next termination

                                              * parameter if IO_LINK set */

    }DV_TPT;




5.4.3. DV_TPT Parameters

Parameter	Description
tp_type	Describes whether the structure is part of a linked list (IO_LINK), part of an array (IO_CONT), or the last DV_TPT entry in the DV_TPT table (IO_EOT).
tp_termno	Specifies what conditions should terminate functions.
tp_length	Specifies the length or size for each termination condition.
tp_flags	Represents various characteristics of the termination condition specified in termno.
tp_data	Specifies optional additional data.
tp_nextp	Contains a pointer to the next DV_TPT structure in a linked list.
