Function Documentation

int htGetError (  HttpProtHandler    this )

returns the error of this. Parameters: this  the struct to be manipulated Returns: error of this

HttpProtHandler htInit (  ConnHandler    parent )

creates, initializes and returns a Http Protokoll Handler. Parameters: parent  Parent ie. caller htInit just initialises some std. values and resets data Returns: an initialized HttpProtHandler Referenced by chInit().

int htIsDataPending (  HttpProtHandler    this )

checks if data is pending. Parameters: this  the struct containing data information Returns: true if data pending, else false Referenced by forwardSendToProtHandler().

int htProcess (  HttpProtHandler    this )

gives the chance to do some internal job. Parameters: this  the struct containing data information gives this the chance to do some internal work. NOTHING IMPLEMENTED NOW Returns: 0 on success, -1 on error (error of this is set to apropriate error) Referenced by chProcess().

int htReceive (  HttpProtHandler    this, struct Buffer    buf )

orders a ProtHandler to Recieve data. Parameters: this  the struct to be manipulated str  the string containing the data to be recieved htRecieve has to be understood as htRecieve!, because it is a call to do so. The data to be recieved is a buffer, which will be processed and validated. Returns: 0 on success, -1 if any error occured (error of this is set to concrete error) Referenced by chReceive().

int htSend (  HttpProtHandler    this, struct Buffer **    buf )

orders a ProtHandler to send buffered data. Parameters: this  the struct containing data information buf  the buffer (pnter), in which the data will be stored htSend has to be understood as htSend!, because it is a call to do so. If data is waiting, it will be stored in buf, else (*buf)->data is set to NULL. Returns: 0 on success, -1 on error (error of this is set to concrete error) Referenced by forwardSendToProtHandler().

int htTerminate (  HttpProtHandler    this )

terminates this. Parameters: this  the struct to be terminated terminates this and frees all allocated memory used by this. Also calls underlying terminate functions Returns: 0 on success, -1 on error (error of this is set to apropriate error) Referenced by chTerminate().
