Jdb_module::Action_code Jdb_bt::action (  int  cmd, void *&  args, char const *&  fmt, int &  next_char )  [virtual]

The actual handler of the module. Parameters: cmd  the command ID (see Cmd::id) of the executed command. args  a reference to the argument buffer pointer. fmt  a reference to the format string pointer. This method is pure virtual and must be provided by the specific derivate of the Jdb_module. action() is called if one of the module's commands was issued and the input according to the format string is read. The args and fmt arguments are references because they may be modified by the action() method and extra input may be requested by returning Action_code::EXTRA_INPUT. In the case where Action_code::EXTRA_INPUT is returned the Jdb_core reads again the values according to the given format (fmt) and enters action(). With this mechanism it is possible to request further input depending on the already given input. Implements Jdb_module.

Jdb_module::Cmd const *const Jdb_bt::cmds (   )  const [virtual]

The commands this module provides. An array of Cmd structures must be returned, where each entry describes a single command. The command IDs (see Cmd::id) should be unique within the module, so that action() can distinguish between the different commands. See also: num_cmds() Cmd action() Implements Jdb_module.

void Jdb_bt::get_user_eip_ebp (  Address &  eip, Address &  ebp )  [static, private]

int const Jdb_bt::num_cmds (   )  const [virtual]

The number of commands this modules provides. This method must return how many Cmd structures can be found in the array returned by cmds(). See also: cmds() Implements Jdb_module.

void Jdb_bt::show (  Mword  ebp, Mword  eip1, Mword  eip2, Address_type  user )  [static, private]

void Jdb_bt::show_item (  int  nr, Address  addr, Address_type  user )  [static, private]

Show one backtrace item we found. Add symbol name and line info
