DESCRIPTION

24       ldns_tcp_send_query()  send a query via tcp to a server. Don't want for
25              the answer
26
27              qbin: the buffer to send
28              sockfd: the socket to use
29              to: which ip to send it
30              tolen: socketlen
31              Returns number of bytes sent
32
33       ldns_tcp_read_wire()     This     routine      may      block.      Use
34              ldns_tcp_read_wire_timeout,  it  checks  timeouts.  Gives back a
35              raw packet from the wire and reads  the  header  data  from  the
36              given socket. Allocates the data (of size size) itself, so don't
37              forget to free
38
39              sockfd: the socket to read from
40              size: the number of bytes that are read
41              Returns the data read
42
43       ldns_tcp_connect() Create a tcp socket to the specified address
44              to: ip and family
45              tolen: length of to
46              timeout: timeout for the connect attempt
47              Returns a socket descriptor
