Thread: Address of Structure element, and struct malloc

Hi there,

I have 2 questsions:

1) How can I access the address of an element of a structure?

I'm trying to do some basic TCP server things, and I have the following struct defined:

Code:

struct clients
{
	char *name;
	char ip[IP]; /*12 digits, 3 '.' and a null character, is the max length of an IP*/
	int new_sd;
	struct sockaddr_in client;
	int client_len;

};
typedef struct clients Clients;

and then I am trying to do something like this:

Code:

int clientCount = 0; /*Keep track of the number of clients connected*/
Clients *clientTable; /*Memory will be dynamically allocated here, as clients connect*/
...
clientTable[clientCount -1].&client = &temp_client;

but I get a syntax error before the & token. I have tried various combinations of brackets, including the & at the beginning followed by brackets, etc.., and cannot get this to compile.
(Note: The -1 is because clientCount is the real number of clients connected. So if 1 client is connected, the actual structure that exists is at clientTable[0])

2) I have an array of these structures, and when I try to book off each element of the array, ie something like:

Code:

clientTable[clientCount -1] = (Clients)malloc(sizeof(Clients));

I get "error: conversion to non-scalar type requested".

Do I not have to malloc memory for this structure? Is it considered already malloc'd just by its creation?

Thanks very much for the help!
