/*************************************************
*     Match a pattern using the DFA algorithm    *
*************************************************/

/* This function matches a compiled pattern to a subject string, using the
alternate matching algorithm that finds all matches at once.

Arguments:
  context       points to a PCRE2 context
  code          points to the compiled pattern
  subject       subject string
  length        length of subject string
  startoffset   where to start matching in the subject
  options       option bits
  match_data    points to a match data structure
  workspace     pointer to workspace
  wscount       size of workspace

Returns:        > 0 => number of match offset pairs placed in offsets
                = 0 => offsets overflowed; longest matches are present
                 -1 => failed to match
               < -1 => some kind of unexpected problem
