Allocates an array of uint8_t at dest, and puts the wireformat of the given rr 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)

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

Parameters
[out]destpointer to the array of bytes to be created
[in]rrthe rr to convert
[in]sectionthe rr section, determines how the rr is written.
[out]sizethe size of the converted result

ldns_status ldns_pkt2wire ( uint8_t **  dest,
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)
