Invalid conversions

[gr8npwrfl]

I am trying to compile this code and I am getting an error I don't understand

Here is the section of code:

int main(int argc, char *argv[])
{
	int sock;
	struct sockaddr_in addr, claddr;
	pid_t pid;
	int i, found;
	int flag;
	int rc;
	pthread_t threadid;

	signal(SIGCHLD, SIG_IGN);

	if (argc >= 2) {
		strcpy(rootdir, argv[1]);
	} else {
		getcwd(rootdir, 512);
	}

	sock = socket(PF_INET, SOCK_STREAM, 0);

	if (sock < 0)
	{
		printf("Error in socket.\n");
		return -1;
	}

	flag = 1;
	if (setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, &flag, sizeof(flag)) < 0)
	{
		printf("Error in setsockopt for REUSEADDR\n");
		return -1;
	}

	addr.sin_family = AF_INET;
	addr.sin_port = htons(7513);
	addr.sin_addr.s_addr = INADDR_ANY;

	if (bind(sock, (struct sockaddr *)&addr, sizeof(addr)) < 0)
	{
		printf("Error in bind\n");
		return -1;
	}

	if (listen(sock, 1) < 0)
	{
		printf("Error in listen\n");
		return -1;
	}

	while (1)
	{
		int consock, size;

		size = sizeof(claddr);
                consock = accept(sock, (struct sockaddr *)&claddr, &size);
		//printf("New connection arriving...\n");
		if (consock < 0)
		{
			printf("Error in accept\n");
			return 0;
		}

And this is the error it says I have.

/home/roger/Nethost/main.cpp|898|error: invalid conversion from ‘int*’ to ‘socklen_t*’|
/home/roger/Nethost/main.cpp|898|error:   initializing argument 3 of ‘int accept(int, sockaddr*, socklen_t*)’|

I am new to programing in C and have never done socket programing before.

Any help would be appreciated

If you mean socklen_t, use socklen_t instead of int.

I don't understand, I highlighted the line that is generating the error.

If you want size to be a socklen_t, if you plan to use size as a socklen_t, then declare it as a socklen_t:

/* not int size; */
socklen_t size;

This code is compiled using C++. And in C++ different types means error (it's pretty much a programming error in C, too, unless you use an explicit cast - and that means you know what you're doing, and in this case, it's WRONG).
accept is expecting the type socklen_t*, but you're passing it int*, which are not the same.
The correct solution then, is what tabstop is pointing out.
