Deallocates resources previously allocated on a d_map_init call.
#include <sys/dma.h> void d_map_clear (*handle) struct d_handle *handle
handle | Indicates the unique handle returned by the d_map_init kernel service. |
The d_map_clear kernel service is a bus-specific utility routine determined by the d_map_init service that deallocates resources previously allocated on a d_map_init call. This includes freeing the d_handle structure that was allocated by d_map_init.
Note: You can use the D_MAP_CLEAR macro provided in the /usr/include/sys/dma.h file to code calls to the d_map_clear kernel service.
The d_map_clear kernel service is part of the base device package of your platform.
