使用Nginx设置fastcgi

Question

I am using following c code

#include <fcgi_stdio.h>

/*
 * 
 */
int main(int argc, char** argv) {
    while (FCGI_Accept() >= 0) {
        printf("Content-Type: text/plain\r\n");
        printf("Hello world in C\n");
    }

    return 0;
}

I am using following command

 spawn-fcgi -a127.0.0.1 -p9000 -n ./a.out

Where spawn-fcgi , I installed using fedora 15 repo.

Nginx config is:

   location / {
        root html;
        fastcgi_pass 127.0.0.1:9000;
        }

I am getting following error:

2012/02/13 16:15:45 [error] 17998#0: *1 upstream closed prematurely FastCGI stdout while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /hello HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "127.0.0.1:8081"

What can be wrong ?

Got the issue code should be

int main(int argc, char** argv) {
    while (FCGI_Accept() >= 0) {
        printf("Content-Type: text/plain\r\n\r\n");
        printf("Hello world in C\n");
    }

    return 0;
}
