Hi,

Take a look at this standalone code, where HTTP POST is successful, but the return code of curl_easy_perform() is always 23 (WRITE ERROR). I need to close stdin, stdout and stderr. If I don't close stdout, return code is 0. Why is this ? And how can I solve this issue ? I'm using libcurl 7.21.1 and RedHat 5. I tried MUTE. but it has been obsoleted. Is there any equivalent options for MUTE ?

#include <stdio.h>
#include <string.h>
#include <curl/curl.h>

// Required by for routine
#include <sys/types.h>
#include <unistd.h>

#include <stdlib.h> // Declaration for exit()

using namespace std;

main()
{

        fclose(stdin);
        fclose(stdout);
        fclose(stderr);

        {
                // Code only executed by child process
                CURL *curl;
                CURLcode res;

                static const char *postthis="moo mooo moo moo";

                curl = curl_easy_init();
                if(curl) {
                        FILE *dr = fopen("./result","w");
                        if (dr != 0) {
                                curl_easy_setopt(curl, CURLOPT_STDERR, dr );
                        }

                        curl_easy_setopt(curl, CURLOPT_URL, "http://www.postbin.org/1boaixh");
                        curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postthis);

                        /* if we don't provide POSTFIELDSIZE, libcurl will strlen() by
                        itself */
                        curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, (long)strlen(postthis));

                        res = curl_easy_perform(curl);

                        fprintf (dr, "Result %d", res );
                        fclose(dr);
                        /* always cleanup */
                        curl_easy_cleanup(curl);
                }
        }
}
