Examples
To start execution of an emulator interface command file at the beginning of
sub-program main5, enter:
Breakpoint Instr main5; cmd_forward ("emul",
"my_command_file")
To provide a target function to send a command to a user interface, compile
the following function into your target program:
void send_command (ui, cmd)
char *ui, *cmd;
{
return;
}
Then set a breakpoint with a macro call:
Breakpoint Instr send_command\@ENTRY; cmd_forward
(ui,cmd)
When execution reaches the first statement in send_command() the command
cmd will be sent to user interface ui. Execution will halt if ui was not attached,
and will continue otherwise.
