Function Documentation

int getAbsPath (  char **    abs_path, const char *    path )

converts path to an absolute path abs_path (if possible). Parameters: abspath  contains the absolute path, after conversion path  the path to be converted into an absolute path converts path into an absolute path abs_path, by combining rootdir and path and then convert it into a valid path Returns: 0 on success, -1 otherwise Definition at line 278 of file reqhandler_file.c. Referenced by rhfInit().

int getSrcInfo (  ReqHandlerFile    this )

puts some information to this. Parameters: this  the data containing the file information reads the source size, the modification date and the extension from the file contained in this Returns: 0 on success, -1 otherwise Definition at line 372 of file reqhandler_file.c. Referenced by rhfInit().

const char* rhfGetAllow (  ReqHandlerFile    this )

returns the allows connected to the file. Parameters: this  the struct to be manipulated Returns: the allows Definition at line 251 of file reqhandler_file.c.

const char* rhfGetContentType (  ReqHandlerFile    this )

returns the files extension. Parameters: this  the struct to be manipulated Returns: the extension, or the file itselfe, if no extension is found Definition at line 257 of file reqhandler_file.c.

int rhfGetError (  ReqHandlerFile    this )

returns the error of this. Parameters: this  the struct to be manipulated Returns: error of this Definition at line 233 of file reqhandler_file.c.

time_t rhfGetModTime (  ReqHandlerFile    this )

returns the files modification date. Parameters: this  the struct to be manipulated Returns: the modification date of the file Definition at line 246 of file reqhandler_file.c.

size_t rhfGetSourceSize (  ReqHandlerFile    this )

returns the file size of the requested file. Parameters: this  the struct to be manipulated Returns: the size of the file Definition at line 241 of file reqhandler_file.c.

ReqHandlerFile rhfInit (  HttpProtHandler    parent, const char *    path_buf, int    change_path )

creates, initializes and returns a file-request Handler. Parameters: parent  Parent ie. caller path_buf  the path of the file (absolute or relative) change_path  if true the path ist converted into an absolute path (/../ is removed), else the path is take as it is rhfInit initialises some std. values and resets data. It also opens a filehandler to be used later. If an error occures, or the file doesnt exist, error is set to the errorcode. Returns: an initialized file-requesthandler Definition at line 110 of file reqhandler_file.c.

int rhfIsDataPending (  ReqHandlerFile    this )

checks if data is pending. Parameters: this  the struct containing data information Returns: true if data pending, else false Definition at line 212 of file reqhandler_file.c.

int rhfModulePreInit (    )

initialize / calculate static values. Returns: 0 on success, -1 on failure Definition at line 87 of file reqhandler_file.c.

int rhfModuleTerminate (    )

free all static ressourcesallocated. Returns: 0 on success, -1 on failure Definition at line 102 of file reqhandler_file.c.

int rhfProcess (  ReqHandlerFile    this )

process some data. 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 concrete error) Definition at line 207 of file reqhandler_file.c.

int rhfReceive (  ReqHandlerFile    this, struct Buffer *    buf )

recieve some data... NOT IMPLEMENTED (only useful for POST). Parameters: this  the struct to be manipulated str  the string containing the data to be recieved rhfRecieve has to be understood as rhfRecieve!, because it is a call to do so. NOTHING IMPLEMENTED NOW (function unused)! Returns: 0 on success, -1 if any error occured (error of this is set to concrete error) Definition at line 166 of file reqhandler_file.c.

int rhfSend (  ReqHandlerFile    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 rhfSend has to be understood as rhfSend!, 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 172 of file reqhandler_file.c.

int rhfTerminate (  ReqHandlerFile    this )

terminates this. Parameters: this  the struct to be terminated terminates this and frees all allocated memory used by this. Returns: 0 on success, -1 on error (error of this is set to concrete error) Definition at line 217 of file reqhandler_file.c.
