ldns_tcp_send_query, ldns_tcp_read_wire, ldns_tcp_connect - tcp queries


#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);


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
