28.2 AL_DemuxDataSet

Prototype C\C++

(16 Bit) ERRNUM AL_DemuxDataSet(LHLD lhld, long lBuffNum,

float _far * DestBuffer, long lStartPoint, long lCount);

(32 Bit) ERRNUM AL_DemuxDataSet(LHLD lhld, long lBuffNum,

float * DestBuffer, long lStartPoint, long lCount);

Visual Basic for Windows

Function AL_DemuxDataSet(ByVal lhld As Long, ByVal lBuffNum As Long,

DestBuffer As Single, ByVal lStartPoint As Long,

ByVal lCount As Long) As Long

LHLD lhld handle of the LDSD

long lBuffNum specifies the buffer number

float _far * DestBuffer destination address to the user buffer

long lStartPoint ADLIB buffer starting point

long lCount conversion count

The AL_DemuxDataSet function converts the selected ADLIB buffer selected by lBuffNum to

Engineering voltage units, placing each samples voltage into the user destination buffer pointed to by

fpfDestBuffer.

Parameter Description

lhld Identifies the instance of the logical device subsystem.

lBuffNum Specifies the buffer ID number.

fpfDestBuffer Points to the destination buffer.

lStartPoint Specifies the starting point in the ADLIB buffer for conversion.

lCount Specifies the number of samples to be converted.

Returns:

On success ERRNUM is set to 1, otherwise ERRNUM contains the last error code that occurred during the

call.
