From a1928bada5edd03fee8aaccce7775c273ae0fcd4 Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Thu, 3 Mar 2005 16:56:53 +0000 Subject: [PATCH] * inferiors.c (change_inferior_id, add_thread, find_inferior_id): Take unsigned long arguments for PIDs. * linux-low.c (add_process, linux_attach_lwp, linux_attach) (linux_thread_alive, linux_wait_for_event, kill_lwp, send_sigstop) (wait_for_sigstop, linux_resume_one_process) (regsets_fetch_inferior_registers, linux_send_signal) (linux_read_auxv): Likewise. Update the types of variables holding PIDs. Update format string specifiers. * linux-low.h (struct process_info, linux_attach_lwp): Likewise. * remote-utils.c (prepare_resume_reply): Likewise. * server.c (cont_thread, general_thread, step_thread) (thread_from_wait, old_thread_from_wait, signal_pid): Change type to unsigned long. (handle_query): Update format specifiers. (handle_v_cont, main): Use strtoul for thread IDs. * server.h (struct inferior_list_entry): Use unsigned long for ID. (add_thread, find_inferior_id, change_inferior_id, cont_thread) (general_thread, step_thread, thread_from_wait) (old_thread_from_wait): Update. * target.h (struct thread_resume): Use unsigned long for THREAD.
