send a query via tcp to a server. Don't want for the answer

.br qbin: the buffer to send .br sockfd: the socket to use .br to: which ip to send it .br tolen: socketlen .br Returns number of bytes sent

This routine may block. Use ldns_tcp_read_wire_timeout, it checks timeouts. Gives back a raw packet from the wire and reads the header data from the given socket. Allocates the data (of size size) itself, so don't forget to free

.br sockfd: the socket to read from .br size: the number of bytes that are read .br Returns the data read

Create a tcp socket to the specified address .br to: ip and family .br tolen: length of to .br timeout: timeout for the connect attempt .br Returns a socket descriptor
