| httr_options {httr} | R Documentation | 
List available options.
Description
This function lists all available options for config().
It provides both the short R name which you use with httr, and the longer
Curl name, which is useful when searching the documentation. curl_doc
opens a link to the libcurl documentation for an option in your browser.
Usage
httr_options(matches)
curl_docs(x)
Arguments
| matches | If not missing, this restricts the output so that either the httr or curl option matches this regular expression. | 
| x | An option name (either short or full). | 
Details
RCurl and httr use slightly different names to libcurl: the initial
CURLOPT_ is removed, all underscores are converted to periods and
the option is given in lower case.  Thus "CURLOPT_SSLENGINE_DEFAULT"
becomes "sslengine.default".
Value
A data frame with three columns:
| httr | The short name used in httr | 
| libcurl | The full name used by libcurl | 
| type | The type of R object that the option accepts | 
Examples
httr_options()
httr_options("post")
# Use curl_docs to read the curl documentation for each option.
# You can use either the httr or curl option name.
curl_docs("userpwd")
curl_docs("CURLOPT_USERPWD")
