NAME
ldns_tcp_send_query, ldns_tcp_read_wire, ldns_tcp_connect-
SYNOPSIS
#include <stdint.h>
#include <stdbool.h>
#include <ldns/ldns.h>
ssize_t ldns_tcp_send_query(ldns_buffer *qbin, int sockfd, const struct sockaddr_storage *to, socklen_t tolen);
uint8_t* ldns_tcp_read_wire(int sockfd, size_t *size);
int ldns_tcp_connect(const struct sockaddr_storage *to, socklen_t tolen, struct timeval timeout);
DESCRIPTION
ldns_tcp_send_query() send a query via tcp to a server. Don't want for the answer
qbin: the buffer to send
sockfd: the socket to use
to: which ip to send it
tolen: socketlen
Returns number of bytes sent
ldns_tcp_read_wire() 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
sockfd: the socket to read from
size: the number of bytes that are read
Returns the data read
ldns_tcp_connect() Create a tcp socket to the specified address
to: ip and family
tolen: length of to
timeout: timeout for the connect attempt
Returns a socket descriptor
