THR: build FAILED - conformance/interfaces/pthread_barrierattr_getpshared/2-1.c

[cocobean]

The process-shared attribute is set to PTHREAD_PROCESS_SHARED to permit a barrier to be operated upon by any thread that has access to the memory where the barrier is allocated. If the process-shared attribute is PTHREAD_PROCESS_PRIVATE, the barrier shall only be operated upon by threads created within the same process as the thread that initialized the barrier; if threads of different processes attempt to operate on such a barrier, the behavior is undefined.

The default value of the attribute shall be PTHREAD_PROCESS_PRIVATE. Both constants PTHREAD_PROCESS_SHARED and PTHREAD_PROCESS_PRIVATE are defined in <pthread.h>.

Steps:

1. Create a piece of shared memory object, create pthread barrier object 'barrier' and set the PTHREAD_PROCESS_SHARED attribute.
2. Parent map the shared memory to its memory space, put 'barrier' into it;
3. Parent fork to create child process;
4. Child process map the 'barrier' to its memory space;
5. Parent and Child execute same code: loop N times, calling pthread_barrier_wait()
6. Parent and Child should not block on pthread_barrier_wait()
