Gdb 3.3 as distributed does not support the attach command to an executing process. The following code (copied from sun3-dep.c with slight renaming of ptrace arguments to match the HP include file) inserted into hp9k320-dep.c after the code for function "kill-inferior" provides a functioning attach command. | #ifdef ATTACH_DETACH | | extern int attach_flag ; | | /* Start debugging the process whose number is PID. */ | | attach (pid) | int pid; | { | errno = 0; | ptrace (PT_ATTACH, pid, 0, 0); | if (errno) | perror_with_name ("ptrace"); | attach_flag = 1; | return pid; | } | | /* Stop debugging the process whose number is PID | and continue it with signal number SIGNAL. | SIGNAL = 0 means just continue it. */ | | void | detach (signal) | int signal; | { | errno = 0; | ptrace (PT_DETACH, inferior_pid, 1, signal); | if (errno) | perror_with_name ("ptrace"); | attach_flag = 0; | } | #endif /* ATTACH_DETACH */ +---------------------------------+----------------------------------+ | David Newton | HPDESK: David Newton/HP1400/B1 | | Hewlett Packard Ltd | ARPA: daven@hpsqf.sqf.hp.com | | Queensferry Telecomms Division | | | South Queensferry | UUCP: ..!hplabs!hpsqf!daven | | West Lothian | JANET: daven@hpqtdla.hp.co.uk | | Scotland EH30 9TG. | PHONE: +44-31-331-7234 | +---------------------------------+----------------------------------+
