# TODO(csilvers): it would be better to actually try to link against
|
|
# -pthreads, to make sure it defines these methods, but that may be
|
|
# too hard, since pthread support is really tricky.
|
|
|
|
# Check for support for pthread_rwlock_init() etc.
|
|
# These aren't posix, but are widely supported. To get them on linux,
|
|
# you need to define _XOPEN_SOURCE first, so this check assumes your
|
|
# application does that.
|
|
#
|
|
# Note: OS X (as of 6/1/06) seems to support pthread_rwlock, but
|
|
# doesn't define PTHREAD_RWLOCK_INITIALIZER. Therefore, we don't test
|
|
# that particularly macro. It's probably best if you don't use that
|
|
# macro in your code either.
|
|
#
|
|
# Note: Cygwin (as of 12/1/08) has a bug in pthread_rwlock, where
|
|
# if you try to acquire a read-lock twice, you get EDEADLCK, where
|
|
# it should succeed. It would be nice to test for that, but we
|
|
# can't do runtime checks here. So we just manually fail for CYGWIN.
|
|
# TODO(csilvers): do better.
