Function Documentation

ast_dns_test_generate_result()

int ast_dns_test_generate_result	(	struct ast_dns_query *	query,
		void *	records,
		size_t	num_records,
		size_t	record_size,
		record_fn	generate,
		char *	buffer
	)

Generate a full DNS response for the given DNS records.

This function takes care of generating the DNS header, question, and answer sections of a DNS response. In order to place test-specific record data into the DNS answers, a callback is provided as a parameter to this function so that the necessary records can be encoded properly by the tests.

There is no buffer size passed to this function. Tests are expected to use a buffer that is sufficiently large for their tests.

Parameters

query	The DNS query that is being processed
records	An array of test-specific representations of DNS records
num_records	The number of elements in the records array
record_size	The size of each element in the records array
generate	The test-specific encoder for DNS records
buffer	The buffer into which to write the DNS response

ast_dns_test_write_domain()

int ast_dns_test_write_domain	(	const char *	string,
		char *	buf
	)

Write a DNS domain to a buffer.

A DNS domain consists of a series of labels separated by dots. Each of these labels gets written as a DNS string. A DNS domain ends with a NULL label, which is essentially a zero-length DNS string.

There is no buffer size passed to this function. Tests are expected to use a buffer that is sufficiently large for their tests.

Parameters

string	The DNS domain to write
buf	The buffer to write the domain into

Returns

The number of bytes written to the buffer

ast_dns_test_write_string()

int ast_dns_test_write_string	(	const struct ast_dns_test_string *	string,
		char *	buf
	)

Write a DNS string to a buffer.

This writes the DNS string to the buffer and returns the total number of bytes written to the buffer.

There is no buffer size passed to this function. Tests are expected to use a buffer that is sufficiently large for their tests.

Parameters

string	The string to write
buf	The buffer to write the string into

Returns

The number of bytes written to the buffer
