cvs commit: apache-apr/pthreads/src/include ap_config.h
rse 99/08/12 00:23:21
Modified: pthreads/src/include ap_config.h
Log:
The additional thread support in ap_config.h:
- NO_SERIALIZED_ACCEPT removes any USE_XXX_SERIALIZED_ACCEPT
to allow one to force no accept serialization without
having to patch the platform specific section.
- A new PTHREAD_EVERYWHERE define which forces pthread.h
to be included into _every_ source file. See the
forthcoming README.rse for details.
