Error with passing a pointer using threads

Question

Updated code: 3/7/11 : 9:29pm

using namespace std;

void * matrixACreate(void * param);  
void *status;

struct a  
{  
     int Arow; // Matrix A    
     i         


        

Answer 1

struct a * a = (struct a *) malloc(sizeof(struct a)); 
// init a's members
error = pthread_create(&matrixAthread, NULL, matrixACreate, a);

EDIT: In response to updated question:

void * matrixACreate(void * param) {  
    struct a * matrix = (struct a *) param;  
    int range = ((matrix->high - matrix->low) + 1);  
    cout << matrix->Arow << endl;  
    return NULL;
}
