    Undeclared identifier error

    Hi, I'm getting the following error:

    Error 1 error C2065: 'szGatewayServer' : undeclared identifier


    Code:
    #define SERVER "test"
    
    struct sTransactionDetails {
    	char szGatewayServer[70];
    };
    
    int ConnectToGateway(int sockfd, char * szGatewayServer);
    
    int main(void) {
       	int sockfd;     
    	struct sTransactionDetails txnDetails;
    	memset(&txnDetails, 0, sizeof(txnDetails));
    	
    	sockfd = CreateSocket();
    
    	strncpy_s(txnDetails.szGatewayServer, sizeof(txnDetails.szGatewayServer), SERVER, strlen(SERVER));
    	ConnectToGateway(sockfd, txnDetails.szGatewayServer);
    	return 0;
    }
    
    
    int ConnectToGateway(int sockfd, char * szGatwayServer) {
    	struct sockaddr_in hints;
    	int state;
    	struct hostent * hostStruct;
    	char ** palias;
    
    	hostStruct = gethostbyname(szGatewayServer);
    
    	for (palias = hostStruct->h_addr_list; *palias != 0; palias++)
    		printf("Host: %s\n", *palias);
    
    	state = connect(sockfd, (const struct sockaddr *)&hints, sizeof hints);
    	if (state == SOCKET_ERROR)
    		return SOCKET_ERROR;
    
    	return 0;
    }
    This is the line where the error is occuring:

    Code:
    hostStruct = gethostbyname(szGatewayServer);
    I don't understand why I'm getting this error... It's more than likely something stupid I can't see but I've been searching for it for like 30 minutes now... Any ideas?

    I've chopped out lots of unnecessary code to try and make it easier to read.

    Thanks.

    You don't have a variable of that name declared. You do have a szGatwayServer, but that's it.

    Good lord. I can't believe I didn't see that. I even rechecked it for that exact reason and still missed it... This is why it helps to have a fresh perspective Thanks tabstop!
