(commune_result): New structure for commune functions. (picom): New enum for commune functions. (_pinfo::hello_pid): New. Pid who's communicating with me. (_pinfo::tothem): New. Handle of communicating pipe. (_pinfo::fromthem): Ditto. (_pinfo::commune_recv): Declare. (_pinfo::commune_send): Declare. (_pinfo::alive): Declare. (_pinfo::cmdline): Declare. (_pinfo::lock): Declare. * pinfo.cc (set_myself): Initialize new _pinfo lock. (_pinfo::alive): Define. Determines if process still exists. (_pinfo::commune_recv): Define. Receive info from another cooperating process. (_pinfo::commune_send): Define. Send info to another cooperating process. (_pinfo::cmdline): Define. Determine command line of a given process. * include/sys/cygwin.h (CW_CMDLINE): Define. *sigproc.cc (talktome): Communicate with any processes who want to talk to me. (wait_sig): Honor __SIGCOMMUNE. * fhandler.cc (fhandler_virtual::fixup_after_exec): Declare. * fhandler_proc.cc: Use malloc/free/realloc throughout rather than cmalloc since buffers don't need to be propagated to subprocesses. * fhandler_registry.cc: Ditto. * fhandler_virtual.cc: Ditto. (fhandler_virtual::fixup_after_exec): Define. * fhandler_process.cc: Ditto for malloc/free/realloc. (process_listin): Add "cmdline". (fhandler_process::fill_filebuf): Implement PROCESS_CMDLINE. * miscfuncs.cc (isalpha_array): New array populated with xor values for alpha characters to switch from one case to another. * string.h (cygwin_strcasematch): New asm implementation of case match. * string.h (cygwin_nstrcasematch): New asm implementation of counted case match. --- winsup/cygwin/external.cc | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'winsup/cygwin/external.cc') diff --git a/winsup/cygwin/external.cc b/winsup/cygwin/external.cc index 571ea6742..406786d7c 100644 --- a/winsup/cygwin/external.cc +++ b/winsup/cygwin/external.cc @@ -241,6 +241,13 @@ cygwin_internal (cygwin_getinfo_types t, ...) extract_nt_dom_user (pw, domain, user); return 0; } + case CW_CMDLINE: + { + size_t n; + pid_t pid = va_arg (arg, pid_t); + pinfo p (pid); + return (DWORD) p->cmdline (n); + } default: return (DWORD) -1; } -- cgit v1.2.3
