diff Python/thread_pthread.h @ 9290:2340f615da8f legacy-trunk
BSDI specific patches, inspired by Nigel Head and otto@mail.olympus.net.
Also (non-BSDI specific):
- Change the CHECK_STATUS() macro so it tests for nonzero error codes
instead of negative error codes only (this was needed for BSDI, but
appears to be correct according to the PTHREADS spec).
- use memset() to zero out the allocated lock structure. Again, this
was needed for BSDI, but can't hurt elsewhere either.
