curldown is this new file format for libcurl man pages. It is markdown inspired with differences: - Each file has a set of leading headers with meta-data - Supports a small subset of markdown - Uses .md file extensions for editors/IDE/GitHub to treat them nicely - Generates man pages very similar to the previous ones - Generates man pages that still convert nicely to HTML on the website - Detects and highlights mentions of curl symbols automatically (when their man page section is specified) tools: - cd2nroff: converts from curldown to nroff man page - nroff2cd: convert an (old) nroff man page to curldown - cdall: convert many nroff pages to curldown versions - cd2cd: verifies and updates a curldown to latest curldown This setup generates .3 versions of all the curldown versions at build time. CI: Since the documentation is now technically markdown in the eyes of many things, the CI runs many more tests and checks on this documentation, including proselint, link checkers and tests that make sure we capitalize the first letter after a period...

# NAME
|
|
|
|
CURLOPT_VERBOSE - verbose mode
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_VERBOSE, long onoff);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Set the *onoff* parameter to 1 to make the library display a lot of
|
|
verbose information about its operations on this *handle*. Useful for
|
|
libcurl and/or protocol debugging and understanding. The verbose information
|
|
is sent to stderr, or the stream set with CURLOPT_STDERR(3).
|
|
|
|
You hardly ever want this enabled in production use, you almost always want
|
|
this used when you debug/report problems.
|
|
|
|
To also get all the protocol data sent and received, consider using the
|
|
CURLOPT_DEBUGFUNCTION(3).
|
|
|
|
# DEFAULT
|
|
|
|
0, meaning disabled.
|
|
|
|
# PROTOCOLS

# EXAMPLE
|

|
|
~~~c

int main(void)

|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
|
|
|
|
/* ask libcurl to show us the verbose output */
|
|
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);
|
|
|
|
/* Perform the request */
|
|
curl_easy_perform(curl);
|
|
}
