Thread: pthread heap separated like stack??

(1)
Is in C/C++ pthreads heap used by malloc/free or new/delete separated (one different heap for each thread) like stacks or not??

(2)
If I use the directives

Code:

#define ALIGN __attribute__ ((aligned (4))) 
typedef struct 
{

    	pthread_t   ALIGN     ThHandle;//not shared
    	sem_t ALIGN Termination;
    	
    	//pthread_mutex_t * BufStatusCommMutex_StatP;//not shared//duplicated
    	Type_SubCamera  Sub;//serialized by MainThread, implicitely (non mutexed) shared by Station and Camera
} ALIGN Type_Camera;

but then I allocate a Type_Camera with new is the alignment respected or not in the heap?
And with malloc()?


thank you
