| 92 |
* For each file you want to parse, call mg_load with the file name. |
| 93 |
* To read from standard input, use NULL as the file name. |
| 94 |
* For additional control over error reporting and file management, |
| 95 |
* use mg_open, mg_read, mg_parse and mg_close instead of mg_load. |
| 96 |
* To pass an entity of your own construction to the parser, use |
| 97 |
* the mg_handle function rather than the mg_ehand routines directly. |
| 98 |
* (The first argument to mg_handle is the entity #, or -1.) |
| 99 |
* To free any data structures and clear the parser, use mg_clear. |
| 100 |
* If there is an error, mg_load, mg_open, mg_parse, mg_handle and |
| 101 |
* mg_fgoto will return an error from the list above. In addition, |
| 102 |
* mg_load will report the error to stderr. The mg_read routine |
