ddi_dma_unbind_handle(9F)				   Kernel Functions for Drivers 				 ddi_dma_unbind_handle(9F)

NAME
ddi_dma_unbind_handle - unbinds the address in a DMA handle SYNOPSIS
#include <sys/ddi.h> #include <sys/sunddi.h> int ddi_dma_unbind_handle(ddi_dma_handle_t handle); PARAMETERS
handle The DMA handle previously allocated by a call to ddi_dma_alloc_handle(9F). INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). DESCRIPTION
ddi_dma_unbind_handle() frees all DMA resources associated with an existing DMA handle. When a DMA transfer completes, the driver should call ddi_dma_unbind_handle() to free system DMA resources established by a call to ddi_dma_buf_bind_handle(9F) or ddi_dma_addr_bind_handle(9F). ddi_dma_unbind_handle() does an implicit ddi_dma_sync(9F) making further synchronization steps unnecessary. RETURN VALUES
DDI_SUCCESS on success DDI_FAILURE on failure CONTEXT
ddi_dma_unbind_handle() can be called from user, kernel, or interrupt context. SEE ALSO
ddi_dma_addr_bind_handle(9F), ddi_dma_alloc_handle(9F), ddi_dma_buf_bind_handle(9F), ddi_dma_free_handle(9F), ddi_dma_sync(9F) Writing Device Drivers SunOS 5.10 26 Sep 1994 ddi_dma_unbind_handle(9F)
