C++ (Cpp) nft_data_reg_snprintf Examples

Example #1

File: bitwise.c Project: bazsi/libnftnl

static int nft_rule_expr_bitwise_snprintf_default(char *buf, size_t size,
						  struct nft_rule_expr *e)
{
	struct nft_expr_bitwise *bitwise = nft_expr_data(e);
	int len = size, offset = 0, ret;

	ret = snprintf(buf, len, "reg %u = (reg=%u & ",
		       bitwise->dreg, bitwise->sreg);
	SNPRINTF_BUFFER_SIZE(ret, size, len, offset);

	ret = nft_data_reg_snprintf(buf+offset, len, &bitwise->mask,
				    NFT_OUTPUT_DEFAULT, 0, DATA_VALUE);
	SNPRINTF_BUFFER_SIZE(ret, size, len, offset);

	ret = snprintf(buf+offset, len, ") ^ ");
	SNPRINTF_BUFFER_SIZE(ret, size, len, offset);

	ret = nft_data_reg_snprintf(buf+offset, len, &bitwise->xor,
				    NFT_OUTPUT_DEFAULT, 0, DATA_VALUE);
	SNPRINTF_BUFFER_SIZE(ret, size, len, offset);

	return offset;
}

Example #2

File: cmp.c Project: alvneiayu/task

{
	int len = size, offset = 0, ret;

	ret = snprintf(buf, len, "\"sreg\" : %u ,\"op\" : \"%s\", \"cmpdata\" : \"",
		       cmp->sreg, expr_cmp_str[cmp->op]);
	SNPRINTF_BUFFER_SIZE(ret, size, len, offset);

	ret = nft_data_reg_snprintf(buf+offset, len, &cmp->data,
