Help: ICE_ICELIB_PIC_DMACHAIN
Set up a DMA chain table entry
Function PIC_DMACHAIN - Set up a DMA chain table entry
PIC p Handle to Device
int dmac DMA Channel - usually returned from PIC_IOPORT
int index Index of this chain entry (1-256)
DMAMAP map DMAMAP structure from PIC_MAPMEM or PIC_MAPFILE
int todo Number of times to execute this chain (-2 for indefinite)
int next Index of the next chain entry (1-256)
This routine is useful for setting up a chain of buffers for continuous
seamless acquisition or playback of multiple host buffers. Index=1 is
automatically linked to the the parent dmac channel. The last entry should
set next=0. Index counts by 1, 2, 3, ... The actual address of each chain
is determined by the libraries. See pic_dmadump() for the actual values.
