vlDMGetParams(3dm)

NAME
     vlDMGetParams - get DMparams list for video subsystem

SYNOPSIS
     #include <dmedia/vl.h>

     int vlDMGetParams(VLServer svr, VLPath path, VLNode node, DMparams * params);

DESCRIPTION
     vlDMGetParams queries the video subsystem for a list of parameters
     describing the characteristics of a specified node and path.  This
     parameter list is required to create a DMbufferpool which can be used for
     video transfers on the same path and memory node.  vlDMGetParams should
     be called after dmBufferSetPoolDefaults(3dm) and before
     dmBufferCreatePool(3dm).

DIAGNOSTICS
     vlDMGetParams returns 0 on success, otherwise -1 is returned and vlErrno
     is set to indicate the error.
