Patrick Scott | 60a4c35 | 2009-07-09 09:30:54 -0400 | [diff] [blame] | 14995 | * This function name is somewhat misleading. It does not clean up |
| 14996 | * parser state, it cleans up memory allocated by the library itself. |
| 14997 | * It is a cleanup function for the XML library. It tries to reclaim all |
| 14998 | * related global memory allocated for the library processing. |
| 14999 | * It doesn't deallocate any document related memory. One should |
| 15000 | * call xmlCleanupParser() only when the process has finished using |
| 15001 | * the library and all XML/HTML documents built with it. |
| 15002 | * See also xmlInitParser() which has the opposite function of preparing |
| 15003 | * the library for operations. |
