Add infrastructure in libps to read this information. * hurd/process.defs (proc_getnports): New RPC. * hurd/process_request.defs (proc_getnports_request): New RPC. * libps/procstat.c (proc_stat_set_flags): Call proc_getnports RPC if needed. * libps/ps.h (proc_stat): New `num_ports' field. (PSTAT_NUM_PORTS): New macro. (proc_stat_num_ports): New macro. * libps/spec.c (ps_get_num_ports): New function. (ps_num_ports_getter): New variable. (specs): New entry for `ps_num_ports_getter'. * proc/info.c (S_proc_getnports): New function. --- libps/ps.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'libps/ps.h') diff --git a/libps/ps.h b/libps/ps.h index a013c44e..b85ede46 100644 --- a/libps/ps.h +++ b/libps/ps.h @@ -303,6 +303,8 @@ struct proc_stat char *env; /* The length of ENV. */ size_t env_len; + + unsigned num_ports; }; /* Proc_stat flag bits; each bit is set in the FLAGS field if that @@ -340,6 +342,7 @@ struct proc_stat #define PSTAT_OWNER_UID 0x200000 /* The uid of the the proc's owner */ #define PSTAT_UMASK 0x400000 /* The proc's current umask */ #define PSTAT_HOOK 0x800000 /* Has a non-zero hook */ +#define PSTAT_NUM_PORTS 0x4000000 /* Number of Mach ports in the task */ /* Flag bits that don't correspond precisely to any field. */ #define PSTAT_NO_MSGPORT 0x1000000 /* Don't use the msgport at all */ @@ -443,6 +446,7 @@ extern char *proc_stat_state_tags; #define proc_stat_umask(ps) ((ps)->umask) #define proc_stat_tty(ps) ((ps)->tty) #define proc_stat_task_events_info(ps) ((ps)->task_events_info) +#define proc_stat_num_ports(ps) ((ps)->num_ports) #define proc_stat_has(ps, needs) (((ps)->flags & needs) == needs) /* True if PS refers to a thread and not a process. */ -- cgit v1.2.3
