When debugging a multi-threaded application on GNU/Linux, GDB now uses '/proc', in preference to 'ptrace' for memory reads. ...... It's annoounced by Mr.Andrew Cagney. May I ask any questions about: 1) Is it the same as multi-process application debugging on GNU/Linux? 2) Does gdb stop the running process by '/proc'? 3) Please tell me how to do, if gdb can't stop it by /proc interface. ______________________________________ =================================================================== ¶©·Ç³£Ð¦»°³é´ó½± ²ÊÆÁÊÖ»úÒ»ÌìÒ»²¿!
