int OverheadVisionClientWifi::recv (  void   )  [virtual]

Reads vision packets from the server from the vision server. This function will block waiting for data from the network, but may return 0 if data is recieved. but it doesn't contain an entire packets worth of data. Returns: <negative value for errors, 0 if no data (or incomplete packet) is recieved, positive value if something is received> Author: <author name>=""> Implements OverheadVisionClient. Definition at line 234 of file overhead_vision_wifi.cpp. References recvInternal(). Referenced by tcpRecv(), and udpRecv().

int OverheadVisionClientWifi::recvInternal (  struct timeval *  selectTO, int  recv_flags )  [protected]

Internal function for recieving data from the vision server from either the udp or tcp socket. This function is for internal use, it can be blocking or non-blocking Parameters: <selectTO>  <pointer to timeval struct, for timeout for select, use NULL if there is no timeout> <recv_flags>  <should be 0 for blocking or O_NONBLOCK for non-blocking sockets> Returns: <negative value for errors, 0 if there was no data (for non-blocking), or > 0 if data was recieved> Author: <Derek> Definition at line 167 of file overhead_vision_wifi.cpp. References maxFD, tcpRecv(), tcpSock, udpRecv(), and udpSock. Referenced by recv(), and recvNoWait().

int OverheadVisionClientWifi::recvNoWait (  void   )  [virtual]

Reads vision packets from the server from the vision server. This function won't block waiting for data. Returns: <negative value for errors, 0 if no data (or incomplete packet) is recieved, positive value if something is received> Author: <Derek> Implements OverheadVisionClient. Definition at line 213 of file overhead_vision_wifi.cpp. References recvInternal().
