Function Documentation

bs_status connect_and_get	(	bs_definition **	result,
		const char *	addr,
		bs_uint16	port,
		apr_pool_t *	mp
	)

Parameters:

	result	Result pointer for the definitions
	addr	The address (IP or hostname) to connect to
	port	TCP/IP port on which the daemon is listening
	mp	Memory pool to allocate from

Returns:

Status code.
