options: API for meta-data about easy options
const struct curl_easyoption *curl_easy_option_by_name(const char *name); const struct curl_easyoption *curl_easy_option_by_id (CURLoption id); const struct curl_easyoption * curl_easy_option_next(const struct curl_easyoption *prev); The purpose is to provide detailed enough information to allow for example libcurl bindings to get option information at run-time about what easy options that exist and what arguments they expect. Assisted-by: Jeroen Ooms Closes #5365

.TH curl_easy_option_by_id 3 "15 May 2020" "libcurl 7.71.0" "libcurl Manual" | ||
.SH NAME | ||
curl_easy_option_by_id - find an easy setopt option by id | ||
.SH SYNOPSIS | ||
.nf | ||
#include <curl/curl.h> | ||
|
||
const struct curl_easyoption *curl_easy_option_by_id(CURLoption id); | ||
.fi | ||
.SH DESCRIPTION | ||
Given a CURLoption \fBid\fP, this function returns a pointer to the | ||
curl_easyoption struct, holding information about the | ||
\fIcurl_easy_setopt(3)\fP option using that id. The option id is the CURLOPT_ | ||
prefix ones provided in the standard curl/curl.h header file. This function | ||
will return the non-aliases version for the cases where there is an alias | ||
function as well. | ||
|
||
If libcurl has no option with the given id, this function returns NULL. | ||
.SH AVAILABILITY | ||
This function was added in libcurl 7.71.0 | ||
.SH RETURN VALUE | ||
A pointer to the curl_easyoption struct for the option or NULL. | ||
.SH "SEE ALSO" | ||

.SH DESCRIPTION | ||
This function returns a pointer to the first or the next curl_easyoption | ||
struct, providing an ability to iterate over all known options for | ||
\fIcurl_easy_setopt(3)\fP in this instance of libcurl. | ||
|
||
Pass a \fBNULL\fP argument as \fBprev\fP to get the first option returned, or | ||
pass in the current option to get the next one returned. If there is no more | ||
option to return, \fIcurl_easy_option_next(3)\fP returns NULL. | ||
|
||
The options returned by this functions are the ones known to this libcurl and | ||
information about what argument type they want. | ||
|
||
If the \fBCURLOT_FLAG_ALIAS\fP bit is set in the flags field, it means the | ||
name is provided for backwards compatibility as an alias. | ||
.SH AVAILABILITY | ||
This function was added in libcurl 7.71.0 | ||
.SH RETURN VALUE | ||
A pointer to the curl_easyoption struct for the next option or NULL if no more | ||
options. | ||
.SH "SEE ALSO" | ||
.BR curl_easy_option_by_name "(3)," curl_easy_option_by_id "(3)," | ||
