/* Modified by anna on 19.01.2009 */
|
|
/*
|
|
canceled SetupParameters() and varaibles intialized in the constructors' headers;
|
|
defined SEND_REC_MAX_SIZE (for compatibilty with mythen (and possibly other) pure C servers (i would move it to the common header file)
|
|
|
|
added #ifndef C_ONLY... to cutout class definition when including in pure C servers (can be removed if SEND_REC_MAX_SIZE is moved to the common header file)
|
|
|
|
defined private variables char hostname[1000] and int portno to store connection informations;
|
|
|
|
defined public functions int getHostname(char *name) and int getPortNumber() to retrieve connection informations
|
|
|
|
added public function int getErrorStatus() returning 1 if socketDescriptor<0
|
|
|
|
remove exits in the constructors and replace them with socketDescriptor=-1
|
|
|
|
replaced the argument of send/receive data with void (to avoid too much casting or compiler errors/warnings)
|
|
|
|
added a function which really does not close the socket between send/receive (senddataonly, receivedataonly)
