gdb小帮手

在LINUX下干活基本不要指望着像在WIN下干活那么舒服。

不同的版本和不同的库都可能会引起各种不同的错误现象。一定要有心理准备。

(gdb) p *pid
$15 = {id = 7, feature_offset = -1, feature = "&usr=", ‘\000‘ <repeats 24 times>, feature_len = 0,
  type = 0 ‘\000‘, result_offset = 4, result_len = 32, proto_no = 1,
  fill_fileld = 0x4080b4 <fill_fileld_str>, end_mark = "&", ‘\000‘ <repeats 28 times>, ext = 0x0}
(gdb) set print pretty on   //
(gdb) p *pid
$16 = {
  id = 7,
  feature_offset = -1,
  feature = "&usr=", ‘\000‘ <repeats 24 times>,
  feature_len = 0,
  type = 0 ‘\000‘,
  result_offset = 4,
  result_len = 32,
  proto_no = 1,
  fill_fileld = 0x4080b4 <fill_fileld_str>,
  end_mark = "&", ‘\000‘ <repeats 28 times>,
  ext = 0x0
}
