NAME
ldns_tcp_send_query, ldns_tcp_read_wire, ldns_tcp_connect - tcp queries
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
.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
-
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
.br
sockfd: the socket to read from
.br
size: the number of bytes that are read
.br
Returns the data read
-
ldns_tcp_connect()
- 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
