Function Documentation

int appendHdrField (  BufpList    hdr_list, char *    prefix, char *    data )

add a field. Todo: use a variadic arguments function Definition at line 679 of file http.c. Referenced by buildEntityHeader(), and htRecvLine().

int buildBasicHeader (  HttpProtHandler    this )

builds the standard headerfields. Parameters: this  the Http protocol handler to be manipulated the headerfields are stored in this->hdr_list Returns: 0 on success, -1 otherwise Definition at line 598 of file http.c. Referenced by htRecvLine().

int buildEntityHeader (  HttpProtHandler    this )

builds the three entity header lines used for files. Parameters: this  the Http protocol handler to be manipulated Returns: 0 on success, -1 otherwise Definition at line 649 of file http.c. Referenced by htRecvLine().

int copyRequestLine (  HttpProtHandler    this, struct Buffer *    buf )

copies a logical line from the connection handlers receive buffer to its line buffer as a single null terminated string line breaks are replaced by spaces Returns: 0 on success (line copied), -1 if end of recv buffer but no logical "end of line" encountered Definition at line 474 of file http.c. Referenced by htReceive().

int htGetError (  HttpProtHandler    this )

returns the error of this. Parameters: this  the struct to be manipulated Returns: error of this Definition at line 292 of file http.c.

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 Definition at line 165 of file http.c.

int htIsDataPending (  HttpProtHandler    this )

checks if data is pending. Parameters: this  the struct containing data information Returns: true if data pending, else false Definition at line 251 of file http.c.

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) Definition at line 240 of file http.c.

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) Definition at line 182 of file http.c.

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) Definition at line 208 of file http.c.

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) Definition at line 259 of file http.c.
