- New functions (no-ops) for source code compatibility:
- pthread_getconcurrency
+ pthread_getconcurrency()
(Only returns the value '0' to indicate
that the system default concurrency is
used)
- pthread_setconcurrency
+ pthread_setconcurrency()
(Accepts any value >= 0 but does not
have any effect; always returns '0' or
EINVAL if arg < 0)
- pthread_attr_getscope
- pthread_attr_setscope
+ pthread_attr_getscope()
+ pthread_attr_setscope()
(Currently only return ENOSYS)
+- The following mutex types and related functions are now
+ supported:
+ pthread_mutexattr_gettype()
+ pthread_mutexattr_settype()
+ PTHREAD_MUTEX_DEFAULT
+ PTHREAD_MUTEX_NORMAL
+ PTHREAD_MUTEX_ERRORCHECK
+ PTHREAD_MUTEX_RECURSIVE
+ In this implementation PTHREAD_MUTEX_DEFAULT is
+ mapped to PTHREAD_MUTEX_RECURSIVE for backward
+ compatibility. Note that this mapping is allowed
+ by the Open Group description but that behaviour
+ considered as "undefined" in manual descriptions may
+ be different to some other implementations, eg
+ Solaris.
+
+ PTHREAD_MUTEX_NORMAL will simulate thread deadlock
+ if the owner of a mutex tries to relock it without
+ first unlocking it, however the lock will be released
+ if the owner thread is async-canceled.
+
+- Pthreads-win32 mutexes are now always based on
+ Win32 critical sections. We no longer use Win32
+ mutexes when TryEnterCriticalSection isn't
+ supported.
+ - Thomas Pfaff <tpfaff@gmx.net>
+
Bugs fixed:
--
+- The condition variable and read-write lock functions
+ have been improved. For details re the [fixed] problems
+ in the CV implementation see the file README.CV
