curl\_easy\_getinfo(3) Library Functions Manual curl\_easy\_getinfo(3)

# [NAME](#NAME)

curl\_easy\_getinfo - extract information from a curl handle

# [SYNOPSIS](#SYNOPSIS)

```
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *curl, CURLINFO info, ...);
```

# [DESCRIPTION](#DESCRIPTION)

Get the *info* kept in the *curl* handle. The third argument **MUST** be pointing to the specific type of the used option which is documented in each man page of the *info* option. The data is stored accordingly and can be relied upon only if this function returns CURLE\_OK. Use this function after a performed transfer if you want to get transfer related data.

You should not free the memory returned by this function unless it is explicitly mentioned below.

# [AVAILABILITY](#AVAILABILITY)

Added in curl 7.4.1

# [RETURN VALUE](#RETURN_VALUE)

This function returns a CURLcode indicating success or error.

CURLE\_OK (0) means everything was OK, non-zero means an error occurred, see [*libcurl-errors(3)*](/man/os/curl/libcurl-errors.3). If [*CURLOPT\_ERRORBUFFER(3)*](/man/os/curl/CURLOPT_ERRORBUFFER.3) was set with [*curl\_easy\_setopt(3)*](/man/os/curl/curl_easy_setopt.3) there can be an error message stored in the error buffer when non-zero is returned.
