# NAME
|
||
|
|
|
||
|
|
curl_easy_option_by_id - find an easy setopt option by id
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
const struct curl_easyoption *curl_easy_option_by_id(CURLoption id);

# DESCRIPTION
|
||
|
|
|
||
|
|
Given a *CURLoption* **id**, this function returns a pointer to the
|
||
|
|
*curl_easyoption* struct, holding information about the
|
||
|
|
curl_easy_setopt(3) option using that id. The option id is the CURLOPT_
|
||
|
|
prefix ones provided in the standard curl/curl.h header file. This function
|
||
|
|
returns the non-alias version of the cases where there is an alias function as
|
||
|
|
well.
|
||
|
|
|
||
|
|
If libcurl has no option with the given id, this function returns NULL.
