generate_naptr_record()

static int generate_naptr_record ( void *  dns_record, char *  buf  )

static

Given a NAPTR record, generate a binary form, as would appear in DNS RDATA.

This is part of a DNS answer, specific to NAPTR. It consists of all parts of the NAPTR record, encoded as it should be in a DNS record.

There is no buffer size passed to this function since we provide the data ourselves and have sized the buffer to be way larger than necessary for the tests.

Parameters

string	The NAPTR record to encode
buf	The buffer to write the record into

Returns

The number of bytes written to the buffer

Asynchronous NAPTR resolution thread.

This builds an appropriate DNS response based on the NAPTR records for a given test. Once the records have been created, the records are added to the DNS result

A buffer to place raw DNS records into.

This buffer is way larger than any DNS records we actually wish to create during any of the tests, but that's fine.

test_records

A pointer to an array of records for a test.

Each test is expected to set this pointer to its local array of records and then re-set tis pointer to NULL at the end of the test
