Hi Nick, I have no idea why duplicate the stdout, and seems that no one deals with the stream closing in the library. Please have a look at the main source code, http://www.sfr-fresh.com/unix/www/gcgi-0.9.5.tar.gz:a/libgcgi.a-0.9.5/src/gcgi.c
I guess this is the official website of this library, no activities since 2002. http://freshmeat.net/projects/gcgi/ Doubt that I would get response from them.. My CGI looks like this roughly.. (only the main structure and skip the non-related parts) main() { if(initCgi() != GCGISUCCESS) { return -1; } if ((fs = fopen ("login.html", "r")) == NULL) { return -2; } while ((c = getc (fs)) != EOF) { . putchar(c); . } fclose(fs); freeCgi(); return 0; } This is the example code the developers provided. I use almost the same code flow as theirs. http://www.sfr-fresh.com/unix/www/gcgi-0.9.5.tar.gz:a/libgcgi.a-0.9.5/examples/gcgiFileUploadTest.c Thanks Best regards, honercek On Fri, May 28, 2010 at 2:17 PM, Nick Kew <n...@webthing.com> wrote: > > On 28 May 2010, at 06:23, Chen Chien-Yu wrote: > > > Hi William, > > > > I reckon it should be mod_cgi, the CGI library I use is called "GNU CGI > Library in C, v0.9.5" which has been maintained for many years. > > > > The function below is the way the CGI init and open the stream. > > > > gcgiReturnType > > initCgi( ) > > { > > /* Dup stdout to gcgiOut */ > > gcgifd = dup(fileno(stdout)); > > gcgiOut = fdopen(gcgifd, "w"); > > Huh?
