From 831d6fa520ed43d055924607a2d9be7fcc3813e9 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Wed, 30 Oct 2002 21:05:18 +0000 Subject: * external.cc (cygwin_internal): Implement CW_CMDLINE. * pinfo.h (SIGCOMMUNE): New signal type. (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/fhandler_proc.cc | 14 +++++--------- 1 file changed, 5 insertions(+), 9 deletions(-) (limited to 'winsup/cygwin/fhandler_proc.cc') diff --git a/winsup/cygwin/fhandler_proc.cc b/winsup/cygwin/fhandler_proc.cc index 86c3c81fb..f887e8cb7 100644 --- a/winsup/cygwin/fhandler_proc.cc +++ b/winsup/cygwin/fhandler_proc.cc @@ -327,7 +327,7 @@ fhandler_proc::fill_filebuf () uname (&uts_name); bufalloc = strlen (uts_name.sysname) + 1 + strlen (uts_name.release) + 1 + strlen (uts_name.version) + 2; - filebuf = (char *) cmalloc (HEAP_BUF, bufalloc); + filebuf = (char *) realloc (filebuf, bufalloc); filesize = __small_sprintf (filebuf, "%s %s %s\n", uts_name.sysname, uts_name.release, uts_name.version); } @@ -335,15 +335,13 @@ fhandler_proc::fill_filebuf () } case PROC_UPTIME: { - if (!filebuf) - filebuf = (char *) cmalloc (HEAP_BUF, bufalloc = 80); + filebuf = (char *) realloc (filebuf, bufalloc = 80); filesize = format_proc_uptime (filebuf, bufalloc); break; } case PROC_STAT: { - if (!filebuf) - filebuf = (char *) cmalloc (HEAP_BUF, bufalloc = 2048); + filebuf = (char *) realloc (filebuf, bufalloc = 2048); filesize = format_proc_stat (filebuf, bufalloc); break; } @@ -354,16 +352,14 @@ fhandler_proc::fill_filebuf () * Windows 95/98/me does have the KERNEL/CPUUsage performance counter * which is similar. */ - if (!filebuf) - filebuf = (char *) cmalloc (HEAP_BUF, bufalloc = 16); + filebuf = (char *) realloc (filebuf, bufalloc = 16); filesize = __small_sprintf (filebuf, "%u.%02u %u.%02u %u.%02u\n", 0, 0, 0, 0, 0, 0); break; } case PROC_MEMINFO: { - if (!filebuf) - filebuf = (char *) cmalloc (HEAP_BUF, bufalloc = 2048); + filebuf = (char *) realloc (filebuf, bufalloc = 2048); filesize = format_proc_meminfo (filebuf, bufalloc); break; } -- cgit v1.2.3
