Member Function Documentation

u_int16_t usipp::UDP::get_dstport ( )

Get the destinationport of the UDP-datagram

u_int16_t usipp::UDP::get_len ( )

Return length of UDP-header plus contained data.

u_int16_t usipp::UDP::get_srcport ( )

Get the sourceport of UDP-datagram.

udphdr usipp::UDP::get_udphdr ( )

Return complete UDP header. Usefull for some kinds of ICMP messages

u_int16_t usipp::UDP::get_udpsum ( )

Return the checksum of UDP-datagram.

int usipp::UDP::init_device ( char * dev, int promisc, size_t snaplen ) [virtual]

Initialize a device ("eth0" for example) for packet- capturing. It MUST be called before sniffpack() is launched. Set 'promisc' to 1 if you want the device running in promiscous mode. Fetch at most 'snaplen' bytes per call. Reimplemented from usipp::IP.

UDP & usipp::UDP::operator= ( const UDP & )

Assign-operator

int usipp::UDP::sendpack ( void * payload, size_t paylen ) [virtual]

Send an UDP-datagramm, containing 'paylen' bytes of data. Reimplemented from usipp::IP.

int usipp::UDP::set_dstport ( u_int16_t )

Set the destinationport in the UDP-header.

int usipp::UDP::set_len ( u_int16_t )

Set the length of the UDP-datagramm.

int usipp::UDP::set_srcport ( u_int16_t )

Set the sourceport in the UDP-header.

int usipp::UDP::set_udpsum ( u_int16_t )

Set the UDP-checksum. Calling this function with s != 0 will prevent sendpack() from setting the checksum!!!

int usipp::UDP::sniffpack ( void * buf, size_t buflen ) [virtual]

Capture packets that are not for our host. Reimplemented from usipp::IP.
