This subroutine accesses the point data type, the engineering units label, and a pointer to the conversion expression.

Syntax

int PTMAP_get_eu_info (point_id, expr_ptr, eu_label,

                       eu_type, retstat)

char            *point_id;

char            **expr_ptr;

char            *eu_label;

PTM_DATA_TYPE   *eu_type;

COR_STATUS      *retstat;

Input Arguments

point_id

Point identifier.

Output Arguments

expr_ptr	Pointer to a translated expression in a database. (Space neither has to be allocated or deallocated.)
eu_label	The configured engineering units label.
eu_type	Data type of input value.
Retstat	Pointer to status structure. The following errors may be returned (see Appendix A for an explanation of this code):
	PTMAP_INVAL_POINT_ID
	PTMAP_HAS_NOT_EU_CONV

Return Value
