Threads and all that is wrong with them

[MailBoxHead20]

Okay, I've got an interesting problem...
I have a threaded program, and each thread has several variables that need to be passed into it. Several ints, a float or two, and a matrix. Now, I've gotten my struct built so that I can pass in all these very odd values:

struct thread_struct{
int rows;
int cols;
int sem_int;
float *matrix;
};

//Insert some code in here

float *t_matrix[i][j];
thread_struct *t_type;
(*t_type).cols=j;
(*t_type).rows=i;
(*t_type).sem_int=7;
(*t_type).matrix=(float*)t_matrix;

And then I pass the struct into my thread

pthread_create(&pde_t[0], NULL, t_proc, (void*)&t_type);

Now, my question is HOW do I retrieve all of my info once I get into my thread?

Thanks y'all.

Thanks for your help. Now I just gotta code it.

Um... the structure needs to be dynamic memory, pthread_create only passes a void*:

typedef struct mydata {
    int some_value;
    char buffer[32];
    float etc;
    double just_because;
} MyData;

void* funct(void* arg)
{
    MyData* pdata = (MyData*)arg;

    // do something

    // free data 
    free(pdata);

    return NULL; // this value can be picked up by pthread_join()
}

int main()
{
    pthread_t thr;
    MyData* dyn_data;
    int sts;
    void* ret_sts = NULL;

    dyn_data = malloc(sizeof(MyData));

    // Fill the members

    // call pthread_create
    sts = pthread_create(&thr, NULL, funct, dyn_data);
    if ( sts < 0 )
    { /* complain */ }

    // wait for thread to complete
     pthread_join(thr, &ret_sts);

    return 0;
}
