Actually, I am writing a new spm_malloc() interface for some academic
research reason. The spm_malloc() is going to allocate a small on-chip
memory for multicore.
it looks like: void *spm_malloc(long bytes), I test the function in many
programs, it works ok.
In this example, the malloc() is called like this:
struct queue {
int head, tail;
void ** data;
int size;
int threads;
int end_count;
#ifdef PARALLEL
pthread_mutex_t mutex;
pthread_cond_t empty, full;
#endif //PARALLEL
};
struct queue *chunk_que;
chunk_que = spm_normal_malloc(sizeof(struct queue) * nqueues);
pthread_mutex_init(&que->mutex, NULL);
pthread_mutex_lock(&que->mutex); //The error occurs here!
...
Can you tell me how the malloc() function will do some relationship with the
pthread_mutex_lock() function? I think that is the point. Many thanks.
