Suggestion about including pthread.h (original) (raw)

Hi,

Currently jdk/src/solaris/bin/java_md.c includes <pthread.h> with "#ifdef linux", but BSD, MAC OS, AIX all needs to include pthread.h. To avoid the situation that the ifdef clause becomes longer and longer like "#if defined(linux) || defined(_ALLBSD_SOURCE) || defined(AIX) || defined(OTHERPLATFORMS)", i suggest to use USEPTHREADS already defined in jdk/make/common/Defs-linux.gmk and add a compiler flag if USE_PTHREADS is true. It will look like this: ifeq ($(USE_PTHREADS), true) CPPFLAGS_COMMON += -DUSE_PTHREADS endif

And then all the places need to include pthread.h only needs to use "#ifdef USE_PTHREADS". The files include pthread.h are jdk/src/solaris/bin/java_md.c jdk/src/solaris/native/sun/nio/ch/NativeThread.c jdk/src/solaris/transport/socket/socket_md.c

Any comments?
