NAME

     ddi_dma_free_handle - free DMA handle

SYNOPSIS

     #include <sys/ddi.h>
     #include <sys/sunddi.h>

     void ddi_dma_free_handle(ddi_dma_handle_t *handle);

PARAMETERS

     handle
           A pointer to the  DMA handle previously allocated by a
           call to ddi_dma_alloc_handle(9F).

INTERFACE LEVEL

     Solaris DDI specific (Solaris DDI).

DESCRIPTION

     ddi_dma_free_handle() destroys the  DMA handle pointed to by
     handle.  Any further references to the  DMA handle will have
     undefined results. Note that  ddi_dma_unbind_handle(9F) must
     be  called   prior  to  ddi_dma_free_handle()  to  free  any
     resources the system may be caching  on the handle.

CONTEXT

     ddi_dma_free_handle() can be called from  user,  kernel,  or
     interrupt context.
