 * @brief Must Call this function before use file navigation API.
 * This function will malloc file list buffer, register known file type and initial other resource.
 * @param [in] lMaxParserFileNum Defined the max file list number, we'll malloc buffer size according
 * this, the size is lMaxParserFileNum * (sizeof(PATHTREE) + lMaxFileNameLength) .
 * @param [in] lFileNavBufferSize The malloc file list buffer size. If you want to give the file 
 * list buffer size instead of lMaxParserFileNum, you can set lMaxParserFileNum to 0 and give buffer size.
 * @param [in] lMaxFileNameLength The max long file name is 256, but we needn't so long name most time,
 * so you can input a resonable long name length to save more memory space.
 * @param [in] lFileNavFlag Defined file navigation action, we have following value:
          AUTO_FILTER_NON_ASIIC_NAME  if set this flag, all non asiic character will be deleted from file name.
          AUTO_FILTER_ZERO_CHARACTER  if set this flag, all zero character will be deleted from file name.
          SHOW_FILE_EXTEND_NAME       if not set this flag, file name's postfix will be deleted.
          DYNAMIC_PARSER_FILE_SYSTEM  if not set this flag, we'll search file list once and save first
                                      lMaxParserFileNum files to list and don't search other files any more.
 * @param [in] pFilterPattern Defined which type file will be added to file list, like "MP3;WMA;JPEG". 
 *         system can recognize following file types:
 *         "MP3;WMA;JPG;JPEG;JPE;VOB;BMP;TIF;TIFF;PNG;GIF;AVI;DIV;DIVX;DAT;MPEG;MPG;"
 *         you can call FileNavAddFilter to add new file type to system.
 * @return Return 0 if success or -1 for fail.
