From f308ba93aae9de462b1b46e68b47bd77a843eed6 Mon Sep 17 00:00:00 2001 From: Nicholas Marriott Date: Fri, 9 Dec 2011 16:28:18 +0000 Subject: Change the way the working directory for new processes is discovered. If default-path isn't empty, it is used. Otherwise: 1) If tmux neww is run from the command line, the working directory of the client is used. 2) Otherwise sysctl KERN_PROC_CWD is used to retrieve the current working directory of the process in the active pane. 3) If that fails, the directory where the session was created is used. Support code by Romain Francois, OpenBSD specific bits by me. Note this requires a recent userland and kernel with KERN_PROC_CWD. --- procname.c | 15 ++++++++++++++- 1 file changed, 14 insertions(+), 1 deletion(-) (limited to 'procname.c') diff --git a/procname.c b/procname.c index 30f71847..370fe342 100644 --- a/procname.c +++ b/procname.c @@ -35,7 +35,8 @@ ((p)->p_stat == SSTOP || (p)->p_stat == SZOMB || (p)->p_stat == SDEAD) struct kinfo_proc *cmp_procs(struct kinfo_proc *, struct kinfo_proc *); -char *get_proc_name(int, char *); +char *get_proc_name(int, char *); +char *get_proc_cwd(pid_t); struct kinfo_proc * cmp_procs(struct kinfo_proc *p1, struct kinfo_proc *p2) @@ -130,3 +131,15 @@ error: free(buf); return (NULL); } + +char* +get_proc_cwd(pid_t pid) +{ + int name[] = { CTL_KERN, KERN_PROC_CWD, (int)pid }; + static char path[MAXPATHLEN]; + size_t pathlen = sizeof path; + + if (sysctl(name, 3, path, &pathlen, NULL, 0) != 0) + return (NULL); + return (path); +} -- cgit
