how to pass argument to thread in c code example

Example 1: How to pass a struct value to a pthread in c?

struct my_Struct{
	int val1, val2;
};
void* my_Func(void *received_struct){
  	//Creating a pointer to point to the received struct
	struct my_Struct *struct_ptr = (struct my_Struct*) received_struct;
    printf("Value 1: %d | Value 2: % \n", struct_ptr->val1, struct_ptr->val2);
	//Now use 'struct_ptr->val1', 'struct_ptr->val2' as you wish
}
//In main:
		struct my_Struct mystruct_1[n];
		pthread_create(&thread, NULL, my_Func, &mystruct_1[i]);
		//i is the index number of mystruct_1 you want to send
		//n is the total number of indexes you want

Example 2: thread parameters c

We use "pthread_create" to create a thread, thread id is the first 
argument, NULL is the second argument(which should be some attribute,
but we may not use it), the third argument is the function, then the 
last argument is what we want to pass to the new thread.
