类型参数名称
char *query
const char *modname
482  errs等于0, exitcode等于0, nfound等于0
484  以query循环
485  split等于strpbrk - Find the first occurrence of a set of characters*@cs: The string to be searched*@ct: The characters to search for
486  如果split则split自加等于'\0'

493  vpr_info("query %d: \"%s\"\n", i, query)
495  rc等于ddebug_exec_query(query, modname)
496  如果rc小于0则
497  errs自加
498  exitcode等于rc
499  否则
500  nfound加等于rc
502  i自加
504  vpr_info("processed %d queries, with %d matches, %d errs\n", i, nfound, errs)
