<body class='hmmessage'><div dir='ltr'>Hi,<BR> <BR>I need the deguggee to stop and pass some information to the debugger - if the debugger is attached, that is. And I want to do it from different threads in concurrent manner. So, I thought maybe I use run-time signals on Linux: i.e. the thread would:<BR><ul><li>Fill out some buffer with data the debugger needs to see</li><li>Send signal 35 to itself passing the address of the buffer as a payload: </li></ul> <BR><ul><ul><li><font face="Courier New,sans-serif">sigval value;</font></li><li><font face="Courier New,sans-serif">value.sival_ptr = address;</font></li><li><font face="Courier New,sans-serif">sigqueue(gettid(), 35, value);</font></li></ul></ul><font face="Courier New"></font> <BR><ul><li>In the signal handler just ignore the signal</li></ul> <BR>If debugger is attached, it will see the signal and inspect info->si_value.sival_ptr. But unfortunately LLDB reports only signal number and drops the value on the floor. <BR> <BR>So, is there any other "legal" way to achieve what I need?<BR> <BR>Thanks,<BR>Eugene<BR> </div></body>
