I have a problem. I cant print to fastcgi output stream in the Inline::C function. When i use puts("TEXT") its print to STDOUT, not fastcgi stream. I think i need to setup parameter $out in function "my_print", but i can't understand how to use this parameter in C function? ( i mark it as "???") Do you have ideas? 
use strict;
use IO::Handle;
use CGI::Fast;
use FCGI::ProcManager;
use POSIX qw(setsid);
use Inline (Config =>
                    DIRECTORY => '/tmp/Inline',
           );
use Inline 'C';

my $PROCESSES = 10;
my $SOCKET = "localhost:8000"; 

&main;

sub main {
        my $proc_manager = new FCGI::ProcManager({ n_processes => $PRO
+CESSES});
        my $socket = FCGI::OpenSocket($SOCKET, 100);
        my $request = FCGI::Request(\*STDIN, \*STDOUT, \*STDERR, \%ENV
+, $socket);        
        $proc_manager->pm_manage();
        while($request->Accept() >= 0){
                $proc_manager->pm_pre_dispatch();
                my $cgi = CGI::Fast->new();
                print $out "Content-type: text/html\r\n\r\n";
                my_print_c();
                $proc_manager->pm_post_dispatch();
        }
        FCGI::CloseSocket($socket);
}

Thanks to you ,ikegami. I wrote C function my_print_c() with your help! But i understand that in this function we emulate perl "print". I glad to see that this C function is more fast that perl... but i think if we'll find method to output C char * to FastCGI stream it will be more faster.
