This may be more helpful than just the +return code from \fIcurl_easy_perform(3)\fP and related functions. The buffer +\fBmust be at least CURL_ERROR_SIZE bytes big\fP. + +You must keep the associated buffer available until libcurl no longer needs +it. Failing to do so will cause very odd behavior or even crashes. libcurl +will need it until you call \fIcurl_easy_cleanup(3)\fP or you set the same +option again to use a different pointer. + +Consider \fICURLOPT_VERBOSE(3)\fP and \fICURLOPT_DEBUGFUNCTION(3)\fP to better +debug and trace why errors happen. + +If the library does not return an error, the buffer may not have been +touched. Do not rely on the contents in those cases. +.SH DEFAULT +NULL +.SH PROTOCOLS +All +.SH EXAMPLE +TODO +.SH AVAILABILITY +Always +.SH RETURN VALUE +Returns CURLE_OK +.SH "SEE ALSO" +.BR CURLOPT_DEBUGFUNCTION "(3), " CURLOPT_VERBOSE "(3), " |
