Synopsis:

#include <qvm/vpci.h>

unsigned vpci_cfg_write(void *rw_cfg,
                        const struct qvm_slice_descriptor *desc,
                        const struct qvm_state_block *blk,
                        const void *val)

Arguments:

rw_cfg: A pointer to the device's read/write state.
desc: A pointer to a slice descriptor array.
blk: The operand of the virtual PCI device's vwrite function (vopnd).
val: A pointer to a location from where to get the bytes that are to be written.

Returns:

A bitset of descriptor indexes that were used for the write.
