If the section argument is LDNS_SECTION_QUESTION, data like ttl and rdata are not put into the result

Parameters

[out]	dest	pointer to the array of bytes to be created

		const ldns_pkt *	p,
		size_t *	size
	)

Allocates an array of uint8_t at dest, and puts the wireformat of the given packet in that array.

The result_size value contains the length of the array, if it succeeds, and 0 otherwise (in which case the function also returns NULL)

Parameters

[out]	dest	pointer to the array of bytes to be created
[in]	p	the packet to convert
