CURLOPT_ERRORBUFFER(3)

CURLOPT_ERRORBUFFER(3)     curl_easy_setopt options     CURLOPT_ERRORBUFFER(3)



NAME
       CURLOPT_ERRORBUFFER - error buffer for error messages

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ERRORBUFFER, char *buf);

DESCRIPTION
       Pass  a  char * to a buffer that libcurl may store human readable error
       messages on failures or problems. This may be more  helpful  than  just
       the  return  code  from curl_easy_perform(3) and related functions. The
       buffer must be at least CURL_ERROR_SIZE bytes big.

       You must keep the associated buffer available until libcurl  no  longer
       needs  it.  Failing  to  do so will cause odd behavior or even crashes.
       libcurl will need it until you call curl_easy_cleanup(3) or you set the
       same option again to use a different pointer.

       Do  not  rely  on  the  contents of the buffer unless an error code was
       returned.  Since 7.60.0 libcurl will initialize  the  contents  of  the
       error  buffer  to  an  empty string before performing the transfer. For
       earlier versions if an error code was returned but there was  no  error
       detail then the buffer is untouched.

       Consider  CURLOPT_VERBOSE(3)  and  CURLOPT_DEBUGFUNCTION(3)  to  better
       debug and trace why errors happen.

DEFAULT
       NULL

PROTOCOLS
       All

EXAMPLE
       curl = curl_easy_init();
       if(curl) {
         CURLcode res;
         char errbuf[CURL_ERROR_SIZE];

         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         /* provide a buffer to store errors in */
         curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, errbuf);

         /* set the error buffer as empty before performing a request */
         errbuf[0] = 0;

         /* perform the request */
         res = curl_easy_perform(curl);

         /* if the request did not complete correctly, show the error
         information. if no detailed error information was written to errbuf
         show the more generic information from curl_easy_strerror instead.
         */
         if(res != CURLE_OK) {
           size_t len = strlen(errbuf);
           fprintf(stderr, "\nlibcurl: (%d) ", res);
           if(len)
             fprintf(stderr, "%s%s", errbuf,
                     ((errbuf[len - 1] != '\n') ? "\n" : ""));
           else
             fprintf(stderr, "%s\n", curl_easy_strerror(res));
         }
       }
