From 907dc7d0c9f64d95b6d4da91dab6601d0e6054ec Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Thu, 14 Feb 2002 21:20:06 +0000 Subject: * exceptions.cc (unused_sig_wrapper): Eliminate unused parameter to asm. * external.cc (cygwin_internal): Change CW_STRACE_ON to CW_STRACE_TOGGLE. * strace.cc (strace::hello): Toggle strace on and off. * sync.cc (muto::init): Renamed from constructor. * sync.h (muto::new): Delete. (muto::delete): Ditto. (new_muto): Simplify. Use muto.init for nearly everything. * uinfo.cc (uinfo_init): Avoid closing a NULL handle. * include/sys/cygwin.h (cygwin_getinfo_types): Rename CW_STRACE_OFF to CW_STRACE_TOGGLE. Delete CW_STRACE_OFF. * include/sys/strace.h (strace): Add "inited" field. --- winsup/cygwin/sync.cc | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'winsup/cygwin/sync.cc') diff --git a/winsup/cygwin/sync.cc b/winsup/cygwin/sync.cc index 743ee02e7..1b5145aa4 100644 --- a/winsup/cygwin/sync.cc +++ b/winsup/cygwin/sync.cc @@ -28,18 +28,24 @@ muto NO_COPY muto_start; #undef WaitForSingleObject /* Constructor */ -muto::muto (int inh, const char *s) : sync (0), visits(0), waiters(-1), tid (0), next (NULL) +muto * +muto::init (int inh, const char *s) { + waiters = -1; /* Create event which is used in the fallback case when blocking is necessary */ - if (!(bruteforce = CreateEvent (inh ? &sec_all_nih : &sec_none_nih, FALSE, FALSE, name))) + if (!(bruteforce = CreateEvent (inh ? &sec_all_nih : &sec_none_nih, FALSE, FALSE, NULL))) { DWORD oerr = GetLastError (); SetLastError (oerr); - return; + return NULL; } name = s; + next = muto_start.next; + muto_start.next = this; + return this; } +#if 0 /* FIXME: Do we need this? mutos aren't destroyed until process exit */ /* Destructor (racy?) */ muto::~muto () { @@ -52,6 +58,7 @@ muto::~muto () if (h) CloseHandle (h); } +#endif /* Acquire the lock.
