* To read from standard input, use NULL as the file name. |
| 80 |
|
* For additional control over error reporting and file management, |
| 81 |
|
* use mg_open, mg_read, mg_parse and mg_close instead of mg_load. |
| 82 |
+ |
* To pass an entity of your own construction to the parser, use |
| 83 |
+ |
* the mg_handle function rather than the mg_ehand routines directly. |
| 84 |
+ |
* (The first argument to mg_handle is the entity #, or -1.) |
| 85 |
|
* To free any data structures and clear the parser, use mg_clear. |
| 86 |
|
* If there is an error, mg_load, mg_open, mg_parse, and mg_rewind |
| 87 |
|
* will return an error from the list above. In addition, mg_load |
