- free DMA handle
#include <sys/ddi.h> #include <sys/sunddi.h> void ddi_dma_free_handle(ddi_dma_handle_t *handle);
A pointer to the DMA handle previously allocated by a call to ddi_dma_alloc_handle(9F).
Solaris DDI specific (Solaris DDI).
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.
ddi_dma_free_handle() can be called from user, kernel, or interrupt context.
