5.2.4. el_AssignBuffer

void **

el_AssignBuffer ( long BoardId, long ChannelNumber, long BufferNo, double

ScaleX, double ScaleY, long Reserved1, long Reserved2 );

Assigns a memory buffer to a DMA channel. The scaling factors are fixed to 1.0 .

PARAMETERS:

BoardId : board ID returned by el_OpenHW

ChannelNumber : DMA channel (0,1,2,3)

BufferNo :Buffer number returned by el_CreateMemBuffer

ScaleX : Scaling factor X-size 1.0

ScaleY : Scaling factor Y-size 1.0

Reserved1 : reserved for future use

Reserved2 : reserved for future use

RETURN VALUE:

Pointer to pointer array if OK

0 if ERROR. See el_GetErrorCode for details.
