Field Documentation

◆ curserver

unsigned int dns_transmit::curserver

Index of the server we are currently sending to.

Referenced by dns_transmit_free().

◆ deadline

struct timeval dns_transmit::deadline

Deadline for considering a request timed out.

Referenced by dns_transmit_free(), dns_transmit_get(), and dns_transmit_io().

◆ localip

ipv4addr dns_transmit::localip

The local IP address to transmit with.

Referenced by dns_transmit_free(), and dns_transmit_start().

◆ packet

char* dns_transmit::packet

The received response packet. This will either be NULL or dynamically allocated.

Referenced by dns_ip4_r(), dns_ip6_r(), dns_mx_r(), dns_name4_r(), dns_name6_r(), dns_transmit_get(), and dns_txt_r().

◆ packetlen

unsigned int dns_transmit::packetlen

The length of the received response packet.

Referenced by dns_ip4_r(), dns_ip6_r(), dns_mx_r(), dns_name4_r(), dns_name6_r(), dns_transmit_get(), and dns_txt_r().

◆ pos

unsigned int dns_transmit::pos

Current sending/receiving position within the buffer, for TCP transmissions.

Referenced by dns_transmit_get().

◆ qtype

uint16 dns_transmit::qtype

The requested query type.

Referenced by dns_transmit_start().

◆ query

char* dns_transmit::query

The transmitted query packet. This will either be NULL or dynamically allocated.

Referenced by dns_transmit_free(), dns_transmit_get(), and dns_transmit_start().

◆ querylen

unsigned int dns_transmit::querylen

The length of the transmitted query packet.

Referenced by dns_transmit_free(), dns_transmit_get(), and dns_transmit_start().

◆ s1

int dns_transmit::s1

The socket file descriptor used for data transmission. This will either be 0 or 1 + an open file descriptor. The addition is done to allow the uninitialized state to be all zeros.
