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.
