    What is the implementation of strstr in glibc?

    glibc中strstr的实现是什么?

    Implementation of STRSTR in glibc (string/strstr.c):

    STRSTR在glibc( string / strstr.c )中的实现:

    /* Return the first occurrence of NEEDLE in HAYSTACK.  Return HAYSTACK
       if NEEDLE is empty, otherwise NULL if NEEDLE is not found in
       HAYSTACK.  */
    char *
    STRSTR (const char *haystack_start, const char *needle_start)
    {
      const char *haystack = haystack_start;
      const char *needle = needle_start;
      size_t needle_len; /* Length of NEEDLE.  */
      size_t haystack_len; /* Known minimum length of HAYSTACK.  */
      bool ok = true; /* True if NEEDLE is prefix of HAYSTACK.  */
    
      /* Determine length of NEEDLE, and in the process, make sure
         HAYSTACK is at least as long (nopoint processing all of a long
         NEEDLE if HAYSTACK is too short).  */
      while (*haystack && *needle)
        ok &= *haystack++ == *needle++;
      if (*needle)
        return NULL;
      if (ok)
        return (char *) haystack_start;
    
      /* Reduce the size of haystack using strchr, since it has a smaller
         linear coefficient than the Two-Way algorithm.  */
      needle_len = needle - needle_start;
      haystack = strchr (haystack_start + 1, *needle_start);
      if (!haystack || __builtin_expect (needle_len == 1, 0))
        return (char *) haystack;
      needle -= needle_len;
      haystack_len = (haystack > haystack_start + needle_len ? 1
    		  : needle_len + haystack_start - haystack);
    
      /* Perform the search.  Abstract memory is considered to be an array
         of 'unsigned char' values, not an array of 'char' values.  See
         ISO C 99 section 6.2.6.1.  */
      if (needle_len < LONG_NEEDLE_THRESHOLD)
        return two_way_short_needle ((const unsigned char *) haystack,
    				 haystack_len,
    				 (const unsigned char *) needle, needle_len);
      return two_way_long_needle ((const unsigned char *) haystack, haystack_len,
    			      (const unsigned char *) needle, needle_len);
    }
    

    The implementation of two_way_short_needle and two_way_long_needle can be found in string/str-two-way.h.

    可以在string / str-two-way.h中找到two_way_short_needletwo_way_long_needle的实现。
