Thread: bind() error

Hey guys,
I'm not sure if this is something wrong with xCode or my code itself (or perhaps a permissions issue in mac os x). Anyways my code looks like this:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>
#include <unistd.h>
#include <signal.h>
#include <string.h>
#include <errno.h>

unsigned short port;
int rSocket;
int clientSocket;
int serverSocket;

struct sockaddr_in clientAddr;
struct sockaddr_in serverAddr;

struct equation
{
	float first, second;
	char operation[15];
};

int main (int argc, const char * argv[]) {
	if (argc < 2)
	{
		printf("Usage: calculator [port]\n--using: 65530\n");
		port = 65530;
	}
	else
		port = (unsigned short) atoi(argv[1]);
	
	memset(&serverAddr, 0, sizeof(serverAddr));
	memset(&clientAddr, 0, sizeof(clientAddr));
	serverAddr.sin_family = AF_INET;
	serverAddr.sin_port = htons(port);
	serverAddr.sin_addr.s_addr = htonl(INADDR_ANY);
	serverSocket = socket(AF_INET, SOCK_STREAM, 0);
	//Bind
	if (bind(serverSocket, (struct sockaddr *) &serverAddr, sizeof(serverAddr)) < 1)
	{
		printf("Error: bind()\nError Number:%d\n", errno);
		exit(-1);
	}
	if (listen(serverSocket, 1) < 0)
	{
		printf("Error: listen()\nError Number:%d\n", errno);
		exit(-1);
	}
	for (;;)
	{
		unsigned int length = sizeof(clientAddr);
		if (clientSocket = accept(serverSocket, (struct sockaddr *) &clientAddr, &length) < 0)
		{
			printf("error: accept()\n");
			exit(-1);
		}
		struct equation current;
		printf("%d\n", sizeof(current));
		int bR = 0;
		if (recv(clientSocket, &current, sizeof(current), 0) < 0)
		{
			printf("Error: recv()");
			exit(-1);
		}
		printf("bR: %d\n", bR);
		printf("%f %s %f\n", current.first, current.operation, current.second);
	}
}

Running yields this:

Code:

sudo ./calculator
Usage: calculator [port]
--using: 65530
Error: bind()
Error Number:0

TIA

bind returns 0 on success, yet you consider 0 to be a failure.

I figured that out shortly after posting, and a little banging my head against the wall.

Thanks!
