A small structure that can be optionally filled in when errors, warnings or other messages are generated and returned to user code.
typedef struct {
  raptor_uri *uri;
  const char *file;
  int line;
  int column;
  int byte;  
} raptor_locator;
Location information for an error, warning or information message.
| raptor_uri * uri; | URI of location (or NULL) | 
| const char * file; | Filename of location (or NULL) | 
| int line; | Line number of location (or <0 for no line) | 
| int column; | Column number of location (or <0 for no column) | 
| int byte; | Byte number of location (or <0 for no byte) |

                                             raptor_locator *locator);
Print a raptor locator to a stream.
| stream: | stream to print to | 
| locator: | raptor_locator to print | 
int         raptor_format_locator           (char *buffer,
                                             size_t length,
                                             raptor_locator *locator);
Format a raptor locator as a string.
If buffer is NULL or length is insufficient for the size of the locator, returns the number of additional bytes required in the buffer to write the locator.
| buffer: | buffer to store format | 
| length: | size of buffer | 
| locator: | raptor_locator to format | 
| Returns : | 0 on success, >0 if additional bytes required in buffer, <0 on failure | 
int raptor_locator_line (raptor_locator *locator);
Get line number from locator.
| locator: | locator | 
| Returns : | integer line number, or -1 if there is no line number available | 
int raptor_locator_column (raptor_locator *locator);
Get column number from locator.
| locator: | locator | 
| Returns : | integer column number, or -1 if there is no column number available | 
int raptor_locator_byte (raptor_locator *locator);
Get the locator byte offset from locator.
| locator: | locator | 
| Returns : | integer byte number, or -1 if there is no byte offset available | 
const char* raptor_locator_file (raptor_locator *locator);
Get file name from locator.
| locator: | locator | 
| Returns : | string file name, or NULL if there is no filename available | 
const char* raptor_locator_uri (raptor_locator *locator);
Get URI from locator.
Returns a pointer to a shared string version of the URI in the locator. This must be copied if it is needed.
| locator: | locator | 
| Returns : | string URI, or NULL if there is no URI available |
