_dba_varinfo Struct Reference

#include <vartable.h>

Detailed Description

Holds the information about a DBALLE variable.

It never needs to be deallocated, as all the dba_varinfo returned by DB-ALLe are pointers to memory-cached versions that are guaranteed to exist for all the lifetime of the program.

Data Fields
dba_varcode	var
	The variable code.
char	desc [64]
	The variable description.
char	unit [24]
	The measurement unit of the variable.
int	scale
	The scale of the variable.
int	ref
	The reference value for the variable.
int	len
	The length in digits of the integer representation of this variable (after scaling and changing reference value).
int	bit_ref
	The reference value for bit-encoding.
int	bit_len
	The length in bits of the variable when encoded in a bit string (after scaling and changing reference value).
int	is_string
	True if the variable is a string; false if it is a numeric value.

Field Documentation

dba_varcode _dba_varinfo::var

The variable code.

See DBA_VAR, DBA_VAR_X, DBA_VAR_Y.

char _dba_varinfo::desc[64]

The variable description.

char _dba_varinfo::unit[24]

The measurement unit of the variable.

int _dba_varinfo::scale

The scale of the variable.

When the variable is represented as an integer, it is multiplied by 10**scale

int _dba_varinfo::ref

The reference value for the variable.

When the variable is represented as an integer, and after scaling, it is added this value

int _dba_varinfo::bit_ref

The reference value for bit-encoding.

When the variable is encoded in a bit string, it is added this value
