Description of the typedef for the DV_TP

The typedef for the DV_TPT structure is shown below:

typedef struct DV_TPT {  
   unsigned short  tp_type;            /* Flags describing this structure */  
   unsigned short  tp_termno;          /* Termination parameter number */  
   unsigned short  tp_length;          /* Length of terminator */  
   unsigned short  tp_flags;           /* Term. parameter attributes flag */  
   unsigned short  tp_data;            /* Optional additional data */  
   unsigned short  rfu;                /* Reserved for future use */  
   struct DV_TPT  *tp_nextp;          /* Pointer to next term. parameter if */  
                                       /* IO_LINK is set */  
} DV_TPT;

where:

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.

Depending on the type of device (for example, D/4x, DTI/xxx), these fields can have different values. For a specific example, see the Voice Software Reference: Programmer's Guide.
