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
