.TH CURLOPT_ERRORBUFFER 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_ERRORBUFFER \- set error buffer for error messages
|
||
|
|
.SH SYNOPSIS
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ERRORBUFFER, [argument]);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
Pass a char * to a buffer that the libcurl may store human readable error
|
||
|
|
messages in on failures or problems. 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.
|
||
|
