Hi Vidya,
How about add a wrap function and keep this function (could modify it's name).
static int
test_enqueue_fill() {
uint64_t pattern[3] = {0x0, 0xfedcba9876543210, 0xffffffffffffffff};
int i;
for (i = 0; i < RTE_DIM(pattern); i++) {
ret = test_enqueue_fill_patter(dev_id, vchan, pattern[i]);
if (ret)
return ret;
}
return 0;
}
