函数名称：aa_dfa_match_len - traverse @dfa to find state @str stops at*@dfa: the dfa to match @str against (NOT NULL)*@start: the state of the dfa to start matching in*@str: the string of bytes to match against the dfa (NOT NULL)*@len: length of the string of bytes

函数原型：unsigned int aa_dfa_match_len(struct aa_dfa *dfa, unsigned int start, const char *str, int len)

返回类型：unsigned int

参数：

类型参数名称
struct aa_dfa *dfa
unsigned intstart
const char *str
intlen
403  def等于DEFAULT_TABLE(dfa)
404  base等于BASE_TABLE(dfa)
405  next等于NEXT_TABLE(dfa)
406  check等于CHECK_TABLE(dfa)
407  state等于start
409  如果state恒等于0则返回:0
413  如果tables[YYTD_ID_EC]则
415  equiv等于EQUIV_TABLE(dfa)
416  以len循环match_char(state, def, base, next, check, equiv[(u8) * str++])
419  否则
421  以len循环match_char(state, def, base, next, check, (u8) * str++)
425  返回:state
