If the library does not return an error, the buffer may not have been
touched. Do not rely on the contents in those cases.
In a few rare cases, there is no text string associated with the error in
libcurl and then you may not get a string in the buffer even though it returns
an error. This is considered a bug and we appreciate your reports about these
cases. Anyway, you can avoid problems with these cases in your program by
making sure to clear the first byte of the error buffer before you call
curl_easy_perform().
.IP CURLOPT_STDERR
Pass a FILE * as parameter. Tell libcurl to use this stream instead of stderr
when showing the progress meter and displaying \fICURLOPT_VERBOSE\fP data.
