access or DMA handle
SYNOPSIS
#include <sys/ndifma.h> void ddi_fm_acc_err_clear(ddi_acc_handle_t acc_handle, int version);
void ddi_fm_dma_err_clear(ddi_dma_handle_t dma_handle, int version);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI)
PARAMETERS
acc_handle
Data access handle obtained from a previous call to ddi_regs_map_setup(9F), ddi_dma_mem_alloc(9F), or to a similar function.
DMA handle obtained from a previous call to ddi_dma_mem_alloc(9F) or one of its derivatives.
Version number of ddi_fm_error_t.
DESCRIPTION
