VoDbFieldGet Function

 FUNCTION VoDbFieldGet(
	wFieldPos AS DWORD,
	ptrRetVal REF USUAL
) AS LOGIC

public static bool VoDbFieldGet(
	uint wFieldPos,
	ref Usual ptrRetVal
)

Parameters

wFieldPos

Type: DWord
The position of the field in the record structure for the current work area.

ptrRetVal

Type: Usual
A pointer to a polymorphic value.
This value will receive the requested information if the function is successful and will be unchanged otherwise.
If you just want to retrieve information, this value must be NIL before calling the function.
Although other RDDs may expand on this concept, the supplied RDDs limit using a non-NIL value to a single circumstance in which you can change the information rather than just retrieve it. With the DBS_ALIAS kInfoType, you can specify a non-NIL value, allowing you to specify a string that you can subsequently use to access the indicated field.
